1. The problem statement, all variables and given/known data I'm having a problem with U-Substitution. I get the simple stuff and the trig substitutions, but this problem has been bugging me. Int( X/(x+2)^(1/4)) 2. Relevant equations 3. The attempt at a solution I first tried u=x+2 and then du=dx. I then solved for x, where x= U-2. That put me at Int( (u-2)/(u^(1/4)). And that's where I don't really know how to go on.
