Question

Please help I am really stuck as how to solve this integral. sqrt(x^2+81)/2

Answer 1

We are doing integration by parts. The examples we were given in class do not involve fractions. should I am not sure what to do with the fractions before I attempt it? \[\int\limits \sqrt{(x^2+81)}/2 dx \]

Answer 2

I figure I should take off the square root sign first to make it \[(x^{2}+81)^{(1/2)}\]

Answer 3

is this right? I don't know where to go from here
