1. The problem statement, all variables and given/known data Sorry that I am not up on latex yet, but will describe the problem the best I can. On the interval of a=1 to b= 4 for X. ∫√5/√x. 2. Relevant equations 3. The attempt at a solution My text indicates the answer is 2√5. I have taken my anti derivative and plugged in b and subtracted plugged in a. Perhaps I am having an issue with the exponents. Thanks for any advice.
