A number that when multiplied by itself twice gives you the original number; its symbol is √.

The cube root of a number, n, is a number whose cube is that number. For example, the cube root of 8 is 2, since 2 x 2 x 2 = 8. In general, the cube root of n is a if a

In mathematics, the cube root of a number, denoted \sqrt[3]{x} or x1/3, is the number a such that a3 = x. All real numbers have exactly one real cube root and 2 complex roots, and all nonzero complex numbers have 3 distinct complex cube roots. For example, the real cube root of 8 is 2, because 23 = 8.
