What are the factors of "96" ?  And do any of them have "perfect cube"? (since "96" does not) ??

96:  1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96.___________________________________
Not:  "8" is a perfect cube:  ∛8 = 2 ;

and:  "8 * 12 = 96" ;
_________________________________
  So;  ∛(96) = ∛8 * ∛(12) = 2* ∛(12) .
