17. 6t^3 x 6t^3

(A)12t^3
(B)12t^6
(C)36t^6
(D)36t^9

Is it b or c??
I just need some help understanding if I'm supposed to add or multiply 6 and 6

since multiplication is commutative,

6t^3 * 6t^3 = 6*6 * t^3*t^3 = 36t^6

t^3*t^3 = t*t*t * t*t*t = t^6, not t^9

add exponents when multiplying powers
thank you so much steve
