perfect cube
rembmber (x^m)^n=x^(mn)
so cued would be (x^m)^3=x^(3m)
the exponents must be divisble by 3
well, all the exponents are divisble by 3 except the ones that are 125
check A and C now
see the coefients
12 is not a perfecte cube, A is wrong
answer is C
it can be written in form
(4x⁵)³+(y⁶)³
