# Math Help - First Derivative

1. ## First Derivative

I have to differentiate this equation:
sqrt(y)*y^2 = 4x

not really sure how to go about doing this, havent done this sort of thing for a while, help much appreciated.

$\sqrt{a} = a^{\frac{1}{2}}$

$a^n \times a^m = a^{m+n}$

Once you've got y reduced to a single power use implicit differentiation
