Syntax
Math.pow(number, fraction);
Examples
Math.pow(256, 1/6); //2.5198420997897464 Math.pow(64, 1/4); //2.82842712474619
You can write a generic function to find the nth root a number like this.
var nthRoot = function (n, root) { return Math.pow(n, 1 / root); }; console.log(nthRoot(64,4)) //2.82842712474619
