How do you find the derivative of #f(x) = x^3e^x#? Calculus Basic Differentiation Rules Product Rule 1 Answer Steve M Oct 27, 2016 # f'(x) = 3x^2e^x + x^3e^x # Explanation: You need to use the product rule; # d/dx(uv)=u(dv)/dx+v(du)/dx # # f(x)=x^3e^x # # :. f'(x) = x^3d/dxe^x + e^xd/dxx^3 # # :. f'(x) = x^3e^x + e^x(3x^2) # # :. f'(x) = 3x^2e^x + x^3e^x # Answer link Related questions What is the Product Rule for derivatives?
