What is the derivative of #y=log_3(x)#? Calculus Differentiating Logarithmic Functions Differentiating Logarithmic Functions without Base e 1 Answer Wataru Sep 22, 2014 By Change of Base Formula: #log_bx={log_ax}/{log_ab}#, #y=log_3x={lnx}/{ln3}# By taking the derivative, #y'={1/x}/{ln3}=1/{(ln3)x}# Answer link Related questions What is the derivative of #f(x)=log_b(g(x))# ?
