    Sorry to hear that but you can differentiate it directly Dy/dx=3x^3/[x^3+x^2]^0.5 We use quotient rule when we divide two different functions e.g x/x^2 We use product rule when we multiply two different functions e.g 3x.Cosx We use chain rule when we three variables e.g x, y, t Dy/Dx=Dy/Dt x...
