About Logarithmic Functions: We can say that: y = log a (x) is the same as: x = a y.So for all intents and purposes, a logarithm is an exponent. When we see log a (x), we are asking for the exponent to which the base (a) must be raised to obtain (x). As an example, suppose we see: log 2 (8). We are asking what exponent must the base (2) be raised to, in order to obtain 8.
Solve the following problems using the properties of logarithmic functions. The solutions are provided below each problem.
