Integration when power ends up as 0?

i need to integrate (using substitution) 4(2x+1)^-1
this gives me 1/2 (integral) 4u^0/0
and obviously anything divided by zero is infinite so how do i go about solving this?

What do you get when you differentiate lnx\ln x?

That's not necessarily true since division by zero is undefined rather than just "infinite". You've got the idea that division by zero causes problems and that's what counts, though!

To solve your immediate problem, follow nuodai.
