How do you differentiate #u= 8/(3x^2)#? Calculus Basic Differentiation Rules Chain Rule 2 Answers Alan P. · Becca M. Apr 15, 2015 #u = 8/(3x^2)# could be written as #u = 8/3 x^(-2)# so #(du)/(dx) = (-2)*8/3 x^(-3)# #= - 16/(3x^3)# Answer link Tiago Hands Apr 15, 2015 Answer link Related questions What is the Chain Rule for derivatives?
