The change of base formula of logs means we can find the logarithm of a number using any base simply by changing the base to one we're more familiar with, i.e. the ones that are available to us on our calculator. So of course it goes something like this: After evaluating the logs the resulting numbers are the powers/exponents the base 10 is raised to obtain 16 and 4. We can, of course, represent these in exponential form, in which case we get: Because of the powers of quotients property we could evaluate this as Clearly this is wrong as 4⁴ = 256, and we were originally trying to find log_4(16) using the change of base property, which of course is 2. My question is ________. Why is this incorrect and where is my error/misstep in logic?
