Which expression has been simplified correctly? Show work.

(-3g)^4=-81g^4


(w^3x^2y^2)(w^2x^3y)=w^5x^5y^3


12y^6

------- = 3y^3

4y^2



(a^3b^5)^2 = a^5b^7

Verified Answer :

\((-3g)^{4} = (-3)^{4} (g)^{4} =81 g^{4}\) . . . . . . . . (first option is not correct)
\((w^3x^2y^2)(w^2x^3y)=w^{3+2}x^{2+3}y^{2+1}=w^5x^5y^3\) . . . . . . . . (option 2 is correct)
Simmilarly you can show that the third and fourth options are not correct.
