Example:Finding Cube Root

 Post to:   Explanation:

Cube root

In mathematics, a cube root of a number, denoted or x1/3, is a number a such that a3 = x. (Our solved example in mathguru.com uses this concept)

All real numbers have exactly one real cube root and a pair of complex conjugate roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8 is 2, because 23 = 8.

# Prime factor

In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly, without leaving a remainder. The process of finding these numbers is called integer factorization, or prime factorization.

To shorten prime factorization, numbers are often expressed in powers, so (Our solved example in mathguru.com uses this concept)
