Okay well I have a definite integral with a square root and u of x-1, with x on the outside and a,b values 1,3.

I changed (sqrt)x-1 to (x-1)^1/2 and divided the x by x to get u' or 1, leaving an x on the outside of the integral. I also changed the a,b values to 0,2. and came out with the answer 3x/2 (x-1)^3/2 before continuing is this correct? I just would like to make sure because I have never gotten a problem like this.
