Question

Can someone help me with this one?
Find the derivative...

Answer 1

\[f(x) = (\frac{ 2x+4 }{ x-4})^5\]

Answer 2

Just started derivatives and quite lost

Answer 3

You would need to use chain rule here
\[\frac{d}{dx} (f(g(x)))=f'(g(x)\times g'(x)\]
suppose we have
\[\frac{d}{dx} ( 4x)^3= 3\times(4x)^2 \times \frac {d}{dx} (4x)\]
\[3\times(4x)^2 \times 4 \]
Do you get this?

Answer 4

Iget the 3 x (4x)^2 but why x 4?

Answer 5

that's the derivative of 4x,

Answer 6

Ohh ok

Answer 7

so you have to use the same procedure in your question. Only thing is it's a bit complex

Answer 8

If I do it now on paper could you check my answer? Might take me a minute or two

Answer 9

ok, sure
