Hey guys, so this is my first post so bare with me. I am working a problem set in a precalc workbook and came across this:

(3)(3^{x/2})^{2 }

The answer i always arrive at no matter how I work it comes out 9^x but the answer sheet on the problem set says that it is 3^(x+1).

Can someone give me a break down of how this is worked??? I've scoured everything but the dark web looking for a solution and can find nothing. Further more, I have found that I am having the same issue with every problem of this type. I feel I'm forgetting a simple rule here.

fyi, I am teaching myself calculus as a hobby.

Thanks in Advance,

Joe
