    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?

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