Calculating the Nth Root

To calculating the nth root of a number, there are two simple methods you can use: the caret operator (^) or Excel‘s POWER function. This tutorial will guide you through both approaches.

Let’s calculate the 10th root of the number 1953125.

Using the Caret (^) Operator to Find the Nth Root of a Number

Follow these steps:

1. Enter the equal operator in a cell and reference the number for which you want to calculating the nth root.
2. Add the caret operator (^).
3. Enter an opening parenthesis.
4. Input 1/10 since you want to calculate the 10th root.
5. Finally, close the parentheses and press Enter to get the result.

=A1^(1/10)

If you want to calculate a different root for a number, modify the “nth_root” value in the formula:

=original_number^(1/nth_root)

Ensure that (1/nth_root) is always in parentheses to maintain the correct order of operations in the calculation.

Calculating the Nth Root with the POWER Function

Follow these steps:

1. Enter the POWER function in a cell and an opening parenthesis.
2. In the first argument, reference the original number.
3. In the second argument, input 1/10.
4. Close the parentheses and press Enter to obtain the result.

POWER(A1,1/10)

In this method, you divide 1 by Calculating the nth root to calculate the result. The difference is that you don’t need to use the caret operator.

For both methods, remember to modify the “nth_root” value in the formula to calculate the 4th, 5th, or any other desired root.

Nth Root for a Negative Number

If you have a negative number and want to find Calculating the nth root, you need to use the ABS function. Here are a couple of examples:

=ABS(A1)^(1/10)

=POWER(ABS(A1),1/10)
