## Main Question or Discussion Point

Hey, everyone

I am working on a calc problem, and I have no idea where to start. The integral is

e^x

------------- [division problem]

(25+e^2x)^4

Do I let my u equal to the 25+e^2x? or what...

then after that what do i do.

Thanks for all the help in advance.
