Hi Sonia! I have included two different approaches to this question. You can choose either approach depending on which one you are comfortable with!

If you are good with logarithms, you can use the rules of logarithms to re-express the given expression into simpler expressions to facilitate easier differentiation.

Otherwise, not to worry! You can differentiate the expression directly from scratch, but you must be able to use the chain rule to do the differentiation.

There is a third method to do this, but is beyond the A Maths syllabus so I will not write them here.
