Webb3 feb. 2024 · The Nth Root of a number is a number that is multiplied by itself n times to get the initial value. Have a look at the Wiki page for more information. Use Math.pow () to calculate x to the power of 1 / n which is equal to the nth root of x. const nthRoot = (x, n) => Math.pow( x, 1 / n); let result = nthRoot(81, 4); console.log( result) // 3. WebbIn fact, for every integer k and every n > 1, the n th root of k is either an integer or irrational. One way to prove it is to use exactly the same idea as for proving the square root of 2 is irrational: suppose k n = p q, with p and q integers, relatively prime. Then q n k = p n.
