square root javascript

var x = Math.sqrt(num);let n = 64;
let root = 6;
Math.pow(n, 1/root);
//output 2;console.log(Math.sqrt(4));     // 2
console.log(Math.sqrt(16));    // 4
console.log(Math.sqrt(64));    // 8
console.log(Math.sqrt(100));   // 10let number = 16
Math.sqrt(number);
//output = 4var isSquare = function (n) {
    return n > 0 && Math.sqrt(n) % 1 === 0;
};let n = 64;
