You may be wondering how to use Excel to derive different roots of a number. Finding a square root is easy: you just use the SQRT function. For instance, the following returns the square root of the value in cell B7:
=SQRT(B7)
What about different roots, however? What if you want the fifth root of the value in B7, instead of the square root? Unless you are a math whiz (and I am not), the answer may not be that obvious. All you need to do is raise the value to the power of 1/n. For instance, if you want that fifth root of B7, then you would use the following formula:
=B7^(1/5)
