Best ResponseYou've already chosen the best response.2well i thought 4 is not included , and acc I have diffrenctd , whereas had it been with x^3 , ans would have been diff

Best ResponseYou've already chosen the best response.6\[ f(x) = \frac {5x}{x^3 4} \implies f'(x) = \frac{(x^3 4)\times 5 5x \times(3x)}{(x^3 4)^2} \]

Best ResponseYou've already chosen the best response.2quotient 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 ! :)
