Is prime factorization the best way to find a cube root?

Hmmmmm...  Have not heard of that one !

 

90   prime fact  = 3 x 5 x 2 x3           cube root of 90 =4.48       Well , that didn't help

 

27  prime fact = 3 x 3 x 3                    Cube root of 27 = 3        It worked for that!   Probably not the BEST though.

 

For finding cube roots, the best way is a calulator !!!!
