Question

Help, need guided help with derivative question: I think this is the chain rule but I'm not sure where to start

Answer 1

\[\large y = \frac{ 1 }{ 56 }(8x -3 )^7 +(3 - \frac{ 1 }{ 10x^2 })^{-1}\]

Answer 2

It is the chain rule. Derivative of something like \(\Large [f(x)]^a \) is:

\(\Large a[f(x)]^{a-1}*f'(x) \)

Answer 3

\[\Large{\frac{1}{56}\frac{d}{dx}(8x-3)^7+\frac{d}{dx}\left( 3-\frac{1}{10x^2} \right)^{-1}}\]
