@daytonamisticrip Square root of x is not x to the second power. For example, the square root of 4 is 2, while 4 to the second power is 16. Also, there is no value of x. The question is not to plug in a value for x and simplify the expression, the question is to integrate the function, thereby ending up with another function.
@bigjay I’m sorry I can’t help you right now. I looked at the problem, but nothing jumped out at me as a good way to approach it. Unfortunately, I don’t have the time to sit and mess with it. I’d really love to, because it looks like an interesting question. I will say that my first thought was trig sub, but I’m not sure if it will get you anywhere. The other thing I thought of was to see if you can simplify the expression and go from there.
EDIT – It looks like @PhiNotPi might have beaten me to the second idea.
