How to use exponents in excel

Exponents are simply repeated multiplications. For example, four to the third power (4³) isn’t 4 x 3, it’s 4 x 4 x 4, which equals a total of 64. If that sounds complicated, fear not; Excel can do the heavy lifting for you!

How to Display Exponents in Excel

Before we learn how to use exponents, we’ll start with a quick example of how to type them in Excel. In this case, we’ll need to employ the Superscript function, so we can display the exponent.

To do this, right-click an empty cell, and then select “Format Cells” from the menu.

How to Use Exponents in the Formula Bar

You can also use exponents in the Excel Formula bar. To do so, click the empty cell where you’d like to display the result of a calculation.

How to use exponents in excel

You plug your exponent into the following formula: “=Power(number,power).” We’ll use 10⁴ for our example, so we type “=Power(10,4)” (without the quotation marks) in the formula bar.

How to Use Exponents in an Individual Cell

If you want to perform the calculation inside a cell, you can skip the formula bar entirely and use a bit of Excel shorthand, instead.

To find 10⁵, for example, you could type “=10^5” (again, without the quotation marks), and then press Enter.

Regardless of how you get there, the answer will be the same. If you’re short on time, finding the solution to an exponent in Excel is a quick alternative to manual calculations.

Using Excel Solver

I tried using empty column entry for y in ‘By changing cells’ and Set objective function as LHS of above equation (empty column entry in equation included) equal to value of 97.5 in solver.

It gives no solution

How do I do this?

3 Answers 3

It’s a bit ambiguous what you’re asking.

Literal math interpretation: 100*(e^0.25)*y = 97.5

Then y = 97.5 / ( 100 * exp(.25)) = .759

My guess of what you want: 100*e^(0.25*y) = 97.5

Then y = ln(97.5/100) / .25 = -.101

Another possibility: (100 * e)^(0.25 * y) = 97.5

Then y = (ln(97.5) / ln(100*e)) / .25 = 3.268

Whatever it is, this doesn’t need solver!

You don’t really need the solver. Just re-arrange your formula to solve for Y. Since y = b^x is the same as log(b)Y = x (log of Y , with base b )

Your formula above is the same as:

(Read aloud, that’s log of 97.5, with base 100e, divided by .25

So, Y = 3.268305672

(Bonus points for someone who can tell me how to format this so the Log looks correct)

The question is “How do I solve this exponential equation on Excel Solver?” which is a fair enough question, as it points to trying to understand how to set up solver.

My interpretation of the equation provided is given in this screenshot .

The solver dialog box is then setup as follows .

How to use exponents in excel

  • This is a non-linear equation and needs GRG Nonlinear. If you choose LP Simplex, it will not pass the linearity test.
  • Ensure “Make Unconstrained Variables Non-Negative” is not checked.

It provided this result for me .

A more precise answer can be obtained by decreasing the “Convergence” value on the GRG Non-Linear Options dialog.

A problem this simple can also be solved using Goal Seek.

Users can use exponents in Excel by using these two methods. You can add any mathematical concept or calculation. You can give any power to the number and later use it for total.How to use exponents in excel

How to Use Exponents in Excel – Top 2 Methods

These two methods are easy to follow and you can use exponents in Excel easily.

  1. Using the POWER function
  2. Using CARET (^) character on the keyboard

When it comes to mathematical concepts, those tiny numeral superscripts called exponents can intimidate even the most earnest student. Exponents in Maths and Exponents in Excel are used for the same function i.e. when you want to multiply a number by itself a given number of times.

The only difference that lies in the usage of Exponents in Excel. There are different ways we can perform the same function. Excel mainly provides two different ways to use exponents in Excel.

Using the POWER function

Excel has numerous mathematical functions from basics to the complex. One of the functions is the POWER function.

  • The Excel POWER function returns the result of taking the power of a number. The function necessitates two arguments, the base, which is the number to be multiplied and the power, which is also referred to as the exponent.

To demonstrate how to use POWER function, consider the result of taking five to the power of two, enter POWER(5,2) in a cell on an Excel spreadsheet preceding with “=” if it’s the first entry in a cell. The result should be 25.

  • You can also use cell references as arguments for the POWER function.

For example, if you want to calculate an exponent for the number in cell A1, you could enter POWER (A1, 5). For an absolute reference to cell A1, use a $ sign before a column label in the arguments, such as $A$1. It will not change if the formula is copied or moved. But without the $, the position of the referenced cell will change.

Using CARET (^) character on the keyboard

You can use it in the way you use in solving your mathematical equations, similar to this 5^2.

The symbol used to define exponents in an equation is called the CARET sign (^). It is available just above the number 6 in your keyboard.

  • Using POWER function is effortless but if you like an even fleeter method, use the caret character (^) on your keyboard to indicate an exponent, such as 5^2. It will translate as five raised to the power of two.
  • You can use cell references instead of using numbers. Like if you consider A1^A2 for reference. It means that the number in the cell A1 would be considered as the base and it would be raised to the power of a number in the cell A2.

You can go for the ways as mentioned above of using the Exponents in Excel.

You may get confused with the EXP function in Excel. You may also think that it is another way out for using a function similar to exponents as its name. So let me help you out with your confusion.

It is a logarithmic function, not an exponent function. The EXP function is used to take the power of e, where e is the constant number 2.71828182845904 (the base of the natural algorithm).

Conclusion

Exponents are useful in business, many important calculations, such as growth projections, and if you are keen Microsoft Excel user, you will likely eventually need to use exponents in Excel. I have covered the best two ways to use exponent in Excel. These are simple and easy to implement ways you can try if you ever faced the difficulty regarding the same.

Spreadsheets are excellent tools to perform financial calculations with if you know the right formulas and how to set them up. For instance, to calculate compounded or simple interest on an investment, you need to know how to work with formulas containing exponents. Fortunately, Excel simplifies the task by providing built-in functions such as POWER you can insert into your equations.

Using the POWER Function

Step 1

Step 2

Click “Blank Workbook” to start a new Excel document.

Step 3

Click an empty spreadsheet cell.

Step 4

Click the “Insert” tab, then click “Function.”

Step 5

Click the “Pick a Category” drop-down list and select “Math & Trig.”

Step 6

Select “POWER” from the list of functions.

Step 7

Type the number you will use as the base after the open parenthesis symbol, a comma, and then the power or exponent you will raise the base to. For instance, if you want to calculate two to the third power, your formula should be “POWER(2,3).”

Step 8

Press the “Enter” key to accept the formula and perform the calculation.

Using the Caret Power Symbol

Step 1

Step 2

Click “Blank Workbook” to start a new Excel document.

Step 3

Click an empty spreadsheet cell.

Step 4

Type “=” (without quotation marks), the base number, a caret and the exponent into the empty cell. For instance, if you want to calculate two to the third power, type “=2^3” (without quotation marks) into a spreadsheet cell.

Step 5

Press the “Enter” key to accept the formula and perform the calculation.

  • Format spreadsheet cells containing the results of financial calculations as “Currency” or “Accounting.” Large numbers produced using the POWER function are displayed in scientific notation by default, even if you increase the size of the cell. In addition, if a cell displays a string of “#” symbols instead of actual numbers, increase the cell’s width.
  • When you format a cell as currency, the number displayed may not be the actual number Excel calculated internally. Excel rounds the value of cells formatted as currency to the nearest hundredth. For instance, if you format a cell containing the function “=POWER(21.57,2)” as currency, Excel displays “$465.26.” The same cell formatted as “General” displays “465.2649.” If you use the rounded result in subsequent calculations by typing it into another cell, you may introduce compounded rounding errors that undermine the accuracy and validity of your work. To prevent this, use a cell’s references rather than its displayed value.

He holds a Bachelor of Science from UNC-Chapel Hill and AAS degrees in office technology, mechanical engineering/drafting and internet technology. Allen has extensive experience with desktop and system software for both Windows and Linux operating systems.

The Scientific format displays a number in exponential notation, replacing part of the number with E+ n, in which E (exponent) multiplies the preceding number by 10 to the nth power. For example, a 2-decimal scientific format displays 12345678901 as 1.23E+10, which is 1.23 times 10 to the 10th power.

Follow these steps to apply the scientific format to a number.

Select the cells that you want to format. For more information, see Select cells, ranges, rows, or columns on a worksheet.

Tip: To cancel a selection of cells, click any cell on the worksheet.

On the Home tab, click the small More button next to Number.

In the Category list, click Scientific.

Using the small arrows, specify the Decimal places that you want to display.

Tip: The number that is in the active cell of the selection on the worksheet appears in the Sample box so that you can preview the number formatting options that you select.

Also, remember that:

To quickly format a number in scientific notation, click Scientific in the Number Format box ( Home tab, Number group). The default for scientific notation is two decimal places.

A number format does not affect the actual cell value that Excel uses to perform calculations. The actual value can be seen in the formula bar.

The maximum limit for number precision is 15 digits, so the actual value shown in the formula bar may change for large numbers (more than 15 digits).

To reset the number format, click General in the Number Format box ( Home tab, Number group). Cells that are formatted with the General format do not use a specific number format. However, the General format does use exponential notation for large numbers (12 or more digits). To remove the exponential notation from large numbers, you can apply a different number format, such as Number.

In Excel, the Power function returns the result of a number raised to a given power.

The syntax for the Power function is: Power (number, power) , number is a base number, power is the exponent used to raise the base number to.

For example, Power (10, 2), the number 10 is the base and the number 2 is the exponent. The calculating result is 100.

Now, I have a range numbers (A1:A15), and I want to get these numbers of 3 power.

You can use this function with the following steps:

1. In adjacent blank cell C1, enter this formula: =Power (A1, 3) , see screenshot:

This tutorial demonstrates how to use the Excel EXP Function in Excel to calculate the exponential value.

How to use exponents in excel

EXP Function Overview

The EXP Function Calculates the exponential value for a given number.

To use the EXP Excel Worksheet Function, select a cell and type:

(Notice how the formula inputs appear)

EXP Function Syntax and Inputs:

number – A number.

What is the EXP function?

The EXP function falls under the category of Math and Trigonometry Functions in Microsoft Excel, which includes LOG and LN. All these functions are related by the ‘natural number’, e, equal to approximately 2.71828. The inverse of EXP is the LN function, meaning that if you input a number into the the LN function and then nest that inside the EXP function, you will get your original number back:

How to use exponents in excel

EXP takes a given real number and raises e to that power.

When would you use the EXP function?

EXP is useful when calculating things to do with growth – crop sizes, bacterial growth, animal populations, and even financial interest.

Common Errors

#NUM – This error occurs when a number too large is input into the EXP function. The smallest value that the EXP function can take is -1×10³⁰⁷ and the largest value is 709.782712893384. But to be honest, when are you going to use numbers that extreme anyway?

For context, e⁷⁰⁹ is equal to about 8×10³⁰⁷ – that’s an 8 with 307 zeroes after it. If that were describing a number of atoms, it would be more than 3 and a half times the number of atoms in the entire universe!

#NAME – This error occurs when the input is not recognized as a number. Unfortunately, that means you cannot calculate e ͥ or Euler’s Identity in MS Excel.How to use exponents in excel

Typo Error – In attempting to bypass the limits of the EXP function, you may be tempted to write your inputs in scientific notation like this: -1E308. As this number will not be recognizable to Excel, a typo error prompt will be shown.

If you accept the correction in the prompt, the formula will use the value in cell E1 as the input. If E1 is zero of blank, this will return the number 5.7903E+133.
If you do not accept the correction, Excel will tell you there is a problem with the formula.

More EXP examples

In 2020 the Coronavirus spread across the planet. The world learned over a period of a couple of months what exponential growth looks like in a real-world setting. Assuming the infection rate, a, is 20%, and there was only one person initially infected with the virus, we can calculate the number of people infected on any given day. Of course, there are problems with this model but it can get us a basic idea.

The equation for working out how many people are infected at any time, t, is given by N = N₀ eᵃᵗ

If we wanted to know the number of infected on day 45 we can use Excel to calculate this:

How to use exponents in excel

So starting with only 1 person infected, and infection rate of 45 days, over 8100 people will be infected by day 45.

We can see how the infections change over time by creating a list of days and calculating each day, then graph the results.

How to use exponents in excel

This graph has similarities with real-world data, but also has some dissimilarities because we haven’t taken into account the real-world consequences of the virus like social distancing measures and fluctuating infection rates. The real-world data shows that while there were only 279 cases 45 days after the first reported case, that quickly increases to 8,000 only ten days later.

As an exercise, see if you can recreate this graph and see the effect of changing the infection rate from 20% down to 18%.

EXP in Google Sheets

The EXP Function works exactly the same in Google Sheets as in Excel:
