[removed] Calculate the nth root of a number

Question

I\'m trying to get the nth root of a number using JavaScript, but I don\'t see a way to do it using the built in Math object. Am I overlooking something?

Answer 1

For the special cases of square and cubic root, it's best to use the native functions Math.sqrt and Math.cbrt respectively.

As of ES7, the exponentiation operator ** can be used to calculate the nth root as the ¹/_nth power of a non-negative base:

let root1 = Math.PI ** (1 / 3); // cube root of π

let root2 = 81 ** 0.25;         // 4th root of 81

This doesn't work with negative bases, though.

let root3 = (-32) ** 5;         // NaN
