Attached in the post are the questions:
Been struggling with the first one for quite a while because there is one cube root inside another. So hopefully someone can help me out with that.
The second question is bugging me as I am unsure whether to use the quotient rule(seeing it is in the form if a fraction) or the chain rule. I would appreciate if someone could offer some advice on what to do and maybe tips on which rule to use in what scenario.
Thanks in advance. Your help will be greatly appreciated.
