Simple integration

S[e^x]=f(u)^n

1. The problem statement, all variables and given/known data
i cannot figure out how to integrate m/(am+bv) with respect to v where a, b and m are constants. i dunno if theres some simple thing i've forgotten but i can't reduce it to a constant and a simple function of v. i'm getting really frustrated as i've been working on the bigger problem (this is only a small fraction of it) for over half an hour now. please help!
