Assuming you mean this as your problem I hope I can assist you.
So just apply the exponent rule to start, which is (a/b)^c = a^c/b^c
This translates to....
Now apply the exponent rule (a^b)^c = a^bc
Which translates to 3^2 * 4 which is refined to 3^8
So now we have....
Just apply the exponent rule (a^b)^c
So we get 2^5 * 4 which refines to 2^20
Therefore our final answer is 2^20/3^8
