Answer:
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.
