Question

How do you differentiate `f(x) = (2x+1)^7` using the chain rule?

Answer 1

You can do it like this:

Explanation:

`f(x)=(2x+1)^7`

Treat `(2x+1)` as it were a single function. Differentiate that and then multiply by the differential of `(2x+1)rArr`

`f'(x)=7(2x+1)^(6)xx2`

`f'(x)=14(2x+1)^6`
