What is the derivative of #f(x) = e^x/lnx#? Calculus Basic Differentiation Rules Product Rule 1 Answer Andrea S. Mar 12, 2018 #d/dx (e^x/lnx) = (e^x(xlnx-1))/(xln^2x)# Explanation: Using the quotient rule: #d/dx (f/g) = (g * (df)/dx -f *(dg)/dx)/g^2# we have: #d/dx (e^x/lnx) = (e^xlnx - e^x/x)/(ln^2x)# #d/dx (e^x/lnx) = (e^x(xlnx-1))/(xln^2x)# Answer link Related questions What is the Product Rule for derivatives?
