How do you differentiate #y= log _5 x#? Calculus Differentiating Logarithmic Functions Differentiating Logarithmic Functions without Base e 1 Answer Henry W. Oct 26, 2016 #(dy)/(dx)=1/(xln5)# Explanation: #y=log_5x=lnx/ln5->#change of base #=1/(ln5)lnx# #(dy)/(dx)=1/ln5*1/x->1/ln5# is a constant, so we don't change it #=1/(xln5)# Answer link Related questions What is the derivative of #f(x)=log_b(g(x))# ?
