\[ f(x) = \frac {5x}{x^3 4} \implies f'(x) = \frac{(x^3 4)\times 5 5x \times(3x)}{(x^3 4)^2} \]

quotient rule : {(dy/dx numerator)*denominator[(dy/dx denominator)*numerator]} / denominator^2 try solving with this , if you get stuck , letme know ! btw FFM has done a great job already , so you wont find any pro ! :)

\[ f(x) = \frac {5x}{x^3 4} \implies f'(x) \] \[= \frac{(x^3 4)\times 5 5x \times(3x^2)}{(x^3 4)^2} = \frac{10 \left(2+x^3\right)}{\left(4+x^3\right)^2} \]
