I think he wants it in simplest form.

One of the ways you could solve this in could be log.

There is nothing to solve Tom because there is no equal sign.  surprise

 

2^(2x+3) -2^(x+2) -3 * 4

 

\(2^{2x+3}-2^{x+2}-3*4\\ 2^{2x+3}-2^{x+2}-12\\ 2^{x+2+x+1}-2^{x+2}-12\\ 2^{x+2}*2^{x+1}-2^{x+2}-12\\ 2^{x+2}(2^{x+1}-1)-12\\ 4*2^x(2*2^x-1)-12\\ 8*2^{2x}-4*2^x-12\\ 8*4^x-4*2^x-12\\ 4(2*4^x-2^x-3)\)

 

 

I am just mucking around.

I really do not know what the question wants.

yea that's what i was thinking as well...i tried to do it with logs but like it doesnt have an equal sign so you can't really do much other than simplify the -3 and 4
