What is the derivative of #y=log_x 2#? Calculus Differentiating Logarithmic Functions Differentiating Logarithmic Functions without Base e 1 Answer Konstantinos Michailidis Oct 12, 2015 We have that from the logarithm change of base formula #log_x2=log2/logx# hence #d(log_x2)/dx=d(log2/logx)/dx=-(log2)/(xlog^2x)# Answer link Related questions What is the derivative of #f(x)=log_b(g(x))# ?
