javascript square root

var x = Math.sqrt(num);let number = 16
Math.sqrt(number);
//output = 4var isSquare = function (n) {
    return n > 0 && Math.sqrt(n) % 1 === 0;
};let n = 64;
let root = 6;
Math.pow(n, 1/root);
// output 2;let n = 64;
let root = 5;
Math.pow(n, 1/root);
// output 2;sqrt("random number, do not put quotes"); //square root
