+2864 I think he wants it in simplest form.
I haven't learned logs yet, so oof
+118687 There is nothing to solve Tom because there is no equal sign. 
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.
