What's your question? Is it that the exponent on x changed from -1/2 to 1/2 or are you unable to understand how ##\frac 1 6 * \frac 1 {1/2} = \frac 1 3##?

If it's the latter, ##\frac a b \cdot \frac c d = \frac{ac}{bc}##.

Have you checked out the khanacademy link that I gave yesterday? Until you get your arithmetic skills up to where they need to be, you won't be able to follow even the simplest calculus explanations.

x didn't change - its exponent changed from -1/2 to 1/2. This was explained in the thread you started yesterday.

##\int x^n dx = \frac{x^{n+1}}{n+1} + C## if n ≠ -1.

Sorry. I remember posting that thread now. Haven't slept in two days.
