The video tutorial explains how to find the derivative of a logarithm with an arbitrary base using the change of base formula. It starts by reviewing the derivative of the natural log and then introduces the change of base formula to express a logarithm with a different base in terms of natural logs. The tutorial demonstrates how to apply this formula to simplify the derivative calculation, ultimately showing that the derivative of log base b of x is 1 over the natural log of b times 1/x.
