find Arc Length of (9-x^(2/3))^(3/2)
I square the second derivative and have it under the square root but then get stuck at (-9x^-1)+x^(-1/3)+1
Help?

I would be confused too.
You have to state the beginning and end of your arc.
Secondly, you didn't state the equation of the graph for which you need the arc length.
I tested your problem with Wolfram, by giving it a function name, and I arbitrarily chose from 2 to 5
here it what the magical website told me
http://www.wolframalpha.com/input/?i=arc+length++%289-x%5E%282%2F3%29%29%5E%283%2F2%29+from+2+to+5
We need more information.
