Derive [itex]y= \sqrt(2x^4) - \frac{5}{3x^2}[/itex]

3. The attempt at a solution

I am still at the first part of the function (the root):

First I tried to derive inside the root like this:

[tex] \sqrt(2x^4) = \sqrt(8x^3) = 2 \sqrt(2) \times \sqrt(x^3) = \sqrt(2) \times x^2[/tex]

Unfortunately, the first part of the function is supposed to be 2\sqrt(2)x.

The second part I am nowhere close yet.
