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