How do you find the derivative of #f(x) = 3x^2 ln 2x#? Calculus Basic Differentiation Rules Product Rule 1 Answer sjc Mar 17, 2018 #f'(x)=(dy)/(dx)=6xln2x+3x# Explanation: we need to use the product rule #d/(dx)(color(red)(u)v)=vcolor(red)((du)/(dx))+color(red)(u)(dv)/(dx)# #d/(dx)(color(red)(3x^2)ln2x)# #(dy)/(dx)=ln2xcolor(red)(d/(dx)(3x^2))+color(red)(3x^2)d/(dx)(ln2x)# #(dy)/(dx)=ln2x xxcolor(red)( 6x)+color(red)(3x^2) xx 1/(2x)xx2# #(dy)/(dx)=6xln2x+3x# Answer link Related questions What is the Product Rule for derivatives?
