...what integral?

do you mean the one you put in the tag? why did you put it there?

anyway, make a substitution $t = \sqrt {x}$ (one way to make this work is to note that $x = \frac {(\sqrt{x})^3}{\sqrt{x}}$. another is to note that you can write $x = (\sqrt{x})^2 = t^2$, and solve for dx in terms of dt). the resulting integral you will be able to do by parts.

can you finish?

Thanks Jhevon, for the reply on the quote. Please finish the assignment so that I can compare with my results.

The other way, you do first your assignment so that Jhevon can compare your result and tell ya if it's right or not.
