I'm having a hard time with this problem:
4^x(times)2^(2x)=16^2
^x means to the x power just in case.
I was able to do a problem before this in the same section. It was:
2^(2x-1)=4
I turn 4 into 2^2 (so there are two 2s on both sides. This way I can make the exponents equal one another and go from there).
So I equal the exponents as stated above and get: 2x-1=2, which comes to 3/2 as the answer. Now I'm not sure how to get use this to solve the problem I typed at the top. Help is appreciated!
