I did all the math already, I guess I should of posted the answer I got (which is why I'm asking for help) to see if I got it right Here is what I got:

The answer I posted above is the overall calculations. The radicals are messing with me I just need to know if I did them right.
note that multiply by to clear the fractions ...
AHH that's what I was missing the radicals always get me. Thanks, I'll redo it and see if I get the same thing, Thanks!
