help asap please thx

Just sub in the numbers and then do the addition.

I will start you off

$\displaystyle{f(x)=x^{(x+1)}(x+2)^{(x+3)}}\\ \displaystyle{f(0)=0^{(0+1)}(0+2)^{(0+3)}}\\ \displaystyle{f(0)=0^{1}*2^3}\\ \displaystyle{f(0)=0}$

Notice that Guest used the word asap in his title. This is one of the things that most answerers don't like.
