1. The problem statement, all variables and given/known data

∫ Sqrt(2x + 7) dx

2. Relevant equations

3. The attempt at a solution

I know that part of it is
(2x+7) ^ 3/2 , but is there a chain rule to it?

It's the chain rule in a way. Put u=2x+7, du=2dx. When you get the answer check it by differentiation and you'll see the chain rule.
