Main Question or Discussion Point

Hi all, I am attempting to learn calculus in my spare time. Very short question. What rule do you use to solve ∫(52x^7/2-66x^5/2+22^3/2)/sqrt(x)? Could you please walk me through it. sorry I didn't use LaTex, I don't know it.

Split up the fraction, and simplify the powers of x first.

If you have a fraction (a+b+c)/d, you may write it as a/d+b/d+c/d

Also, remember that [itex]\sqrt{x}=x^{\frac{1}{2}}[/itex]

A question:
You have a term in your numerator, 22^3/2.
Should that have been: [itex]22x^{\frac{3}{2}}[/itex]?
