x^(1/3)(adsbygoogle = window.adsbygoogle || []).push({});

The only way I have for this on this is to show that the derivative of x^n equals Nx^(n-1).

I can't think of a way to do it in first principles.

If I can just break up (x+h)^1/3, I'm good.

If you break that up, you get...

[tex]x^\frac{1}{3} + 1/3x^\frac{2}{9}h^\frac{1}{9} + 1/3x^\frac{1}{9}h^ \frac{2}{9}+ h^\frac{1}{3}[/tex]

It's probably wrong, but that is all I can think of.

Any pointers would help.
