This function can be written as a composition of two functions, therefore we use the chain rule.
Explanation:
Let
Simplifying further, we have that
The chain rule states
This means we have to differentiate both functions and multiply them. Let's start with
By the power rule
Now for
Once again by the power rule we get:
Hopefully this helps!
