Hi!

Let make a change in the integral like this t=5-y.

So for y=0 -> t=5 and for y=5 -> t=0

dt=-dy and because g(5-y) = - g(y) the new integral is :

     _{5                                        5}
     �ç5^g(y)(1+ 5^g(y))^-1 dy  =    5-�ç(1+ 5^g(y))^-1 dy
      ^{0                                       0}

^{So I = 5-I => I=5/2}
