# Math Help - Tough Integral.

1. ## Tough Integral.

Spoiler:

Is this correct?

Cause the texbook gives.

$(b^{b}a^{-a})^{\frac{1}{b-a}}e^{-1}$

The original question is at the bottom on the picture i posted.

2. Yes thats correct. You can simplify your answer to the one given in the textbook. Remember that $e^{\ln x} = x$ $\, \,$ !

3. correction x not x!, sry, just had to do it
