Explanation:
In mathematics, a cube root of a number, denoted or x^{1/3}, is
a number a such that a^{3} = 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 2^{3} = 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
