Integral help please; relatively simple

  1. Feb 25, 2008 #1
    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.
