Hi,

I really do need to study for Calculus a little more...
How do I find the derivative of 2 over the square root of x?
The answer is negative one over the square root of x^3.

Thank you!

$\frac{d}{dx}\left ( \frac{2}{\sqrt{x}} \right ) = \frac{d}{dx} 2x^{-1/2} = 2\times \frac{-1}{2}x^{-3/2} = -\frac{1}{\sqrt{x^{3}}}$

Thank you! Realised where I was going wrong
