Answer as soon as possible please

a^2*c*8

  9*b^6

Step-by-step explanation:

Recall how we handle the exponents in dealing with power functions:

(ac^4)^2 comes out to a^2*c^8.  We multiply the powers together in this case.

(3b^3)^2 is done the same way:  we get 3^2*b^6.

Therefore, the given expression simplifies to     a^2*c*8

                                                                                  9*b^6

this matches the second answer choice.
