yes....sorry, i know its small, i think you have to click it once to zoom, if you have the option.
Hello janedoe Originally Posted by janedoe http://i33.tinypic.com/2i3e9u.jpg details of my question are in there ^ Thanks in advance If the question is indeed $\displaystyle \int_5^7\sqrt{4+u^5}du$, then I agree with your answer: $\displaystyle 179.567$. I think we have some crossed wires somewhere. Grandad

I'll have to let my teacher know about this mistake. For the record, is that integral easily solved to get the exact answer, or isnt it an elementary function?

Ok, me either, thanks!
