# Problem of the Week

## Updated at Jul 6, 2015 11:43 AM

This week we have another calculus problem:

How would you differentiate $$\frac{1}{{x}^{\frac{11}{2}}}$$?

Let's start!

$\frac{d}{dx} \frac{1}{{x}^{\frac{11}{2}}}$

 1 Use Power Rule: $$\frac{d}{dx} {x}^{n}=n{x}^{n-1}$$.$-\frac{11}{2{x}^{\frac{13}{2}}}$Done-11/(2*x^(13/2))
