    I understand the sample problem. I just don't know how to use it for the actual problem.

    do the same...instead of using 7 use 5

    I did, but it shows up as wrong when I put it in.

    what is the final answer that you got when you did the problem?

    Nevermind, I found my error, instead of 2/9 I put 2/5. Sorry. Can you help me with another problem though?

    yes sure....remember to follow all the steps and make sure you don't make a mistake. One small mistake can make the answer wrong

    What's the first step? Let's make the square root into an exponent \[\int\limits_{3}^{7}\frac{1}{\sqrt{6x+7}}dx\]\[\int\limits_{3}^{7}\frac{1}{(6x+7)^\frac{1}{2}}dx\]

    then we bring the denominator to the top. But in order to do this we have to make the exponent a negative. Then we get \[\int\limits_{3}^{7}(6x+7)^{-\frac{1}{2}}dx\]

    You just integrate what's inside first....can you tell me what you get?

    No that's not it. Look back in the problem you did before and see how they integrated a square root after it became \[(-------)^\frac{1}{2}\]

    you have to do the chain rule.

    I thought you know how to integrate something that was a square root. Look at the example problem you did before and see what happens.

    Would it be: 1/12 root of 6x+7?

    Is the answer 1/4? If yes, then I've done my work correct.

    I think you made a mistake \[\frac{1}{6} *\frac{1}{2}=\frac{1}{12}\] that's how you got the 12 right?

    it's suppose to be\[\frac{1}{6}*2=\frac{2}{3}=\frac{1}{3}\]
