Using this function in a Worksheet is simple; all you need to do is enter the function as a formula of the cell in the formula bar.

Take a look at the given example

To raise the complex number to a certain power, enter the complex numbers in column A and in Column B, enter the power value to which the complex number needs to be raised. In column C, enter the following formula

Formula: =IMPOWER (A1,B1)

Excel does the mathematical calculation internally and returns the result.

Here, A1 refers to the cell name or the cell address. Repeat the same to the other cells and you will get the final results.
