How do you use the nth root?

To use the nth root of a number, you can apply the formula ( \sqrt[n]{x} ), where ( x ) is the number and ( n ) is the degree of the root. This operation finds a value that, when raised to the power of ( n ), equals ( x ). For example, the cube root of 8 is calculated as ( \sqrt[3]{8} = 2 ) since ( 2^3 = 8 ). You can compute nth roots using calculators or programming languages that support exponentiation functions.
