1. The problem statement, all variables and given/known data

The problem is : f(x)= √3 cos^5(sinx²-3/³√x)

2. Relevant equations

The only thing i kno is that f prime of x comes next and thats all.. calculus is kind of confusing but i'll make sure i understand with your help. Thanks in advance

3. The attempt at a solution

S.O.S

Is this the function you want to differentiate?
$$f(x)~=~\sqrt{3}cos^5\left(sin(x^2) - \frac{3}{\sqrt[3]{x}}\right)$$

Or is it this?
$$f(x)~=~\sqrt{3}cos^5\left(sin^2(x) - \frac{3}{\sqrt[3]{x}}\right)$$

Or something else?

Do you know the chain rule?
