# How to Use Excel IMPOWER Function?

Excel is a powerful data visualization tool that offers a variety of built-in formulas and functions for performing mathematical calculations on a spreadsheet. Sometimes, we use complex numbers in the worksheet, In case, you want to raise it to a power, then we suggest you use the Excel IMPOWER Function.

In this post, we are going to explore the usage of  IMPOWER Function in Excel 365 with its syntax, description, and examples. Get an official version of MS Excel from the following link:

## Description of IMPOWER Function

• The IMPOWER Function returns a complex number (X+Yi or X+Yj) raised to a given number.
• X and Y are real numbers, and i or j is an imaginary number.
• X is a real part, Yi is an imaginary part.
• You can use a COMPLEX Function to convert real and imaginary coefficients to a complex number.

## Syntax

• Here, you will see the syntax of the IMPOWER function.
• To apply this function on your spreadsheet, you have to select a cell and enter the formula in the following format.
• Once you enter the formula, just click on the button to get the result.

=IMPOWER(inumber, number)

Argument Explanation:

Inumber – A complex number which you want to raise a power.

Number – It is a Power to raise a complex number.

Note:
1) You can use the COMPLEX function to convert real and imaginary coefficients to a complex number.
2) If the number is a non-numeric value (letters and special characters), it returns #VALUE! Error.
3) You can give the integer, fractional, and negative values to the number argument.
4) Only “i” or “j” is allowed to use in this function, other values will return #NUM! Error.
5) To calculate IMPOWER function, the below formula will be used and so refer to the below image.

## Examples

Let’s see an example to know how IMPOWER Function works in the Excel spreadsheet.

• Initially, you have to open your Excel workbook on your PC and launch a worksheet that has data.
• For example, we have shown you Complex numbers (inumber) in Column A and their Power values (number) in Column B.
• Then, you have to enter the formula in the cell as shown below to get the result.
• After entering the formula, you need to click the button to get the output, as shown below. You can drag down the cell to fill the remaining cells.

## Input that Causes Error

• If the number is a non-numeric value (letters and special characters), it returns #VALUE! Error.
• Only “i” or “j” is allowed to use in this function, other values will return #NUM! Error.
