We will explain the functions for finding powers , square roots , and cube roots .
Functions are provided to find powers, square roots, and cube roots.
In this article, we will explain how to use each function and introduce sample programs.
Functions to find powers, square roots, and cube roots
Use the following Math object methods to calculate powers, square roots, and cube roots.
| method | explanation |
|---|---|
| Math.pow(base, exponent) | Returns the power. Returns base raised to the power of exponent. |
| Math.sqrt(x) | Returns the square root of the given number. It takes one argument, x, and returns the square root of x. |
| Math.cbrt(x) | Returns the cube root of the given number. It takes one argument, x, and returns the cube root of x. |
Below are samples using each method.
console.log(Math.pow(2, 3)); // 8
console.log(Math.sqrt(9)); // 3
console.log(Math.cbrt(8)); // 2You can also use “**” to calculate powers.
console.log(2 ** 3) // 8Available from ES2016, it allows you to calculate powers more concisely than Math.pow().
