WebIn less formal terms, the log rules might be expressed as: 1) Multiplication inside the log can be turned into addition outside the log, and vice versa. 2) Division inside the log can be turned into subtraction outside the log, and vice versa. 3) An exponent on everything inside a log can be moved out front as a multiplier, and vice versa. WebBy establishing the relationship between exponential and logarithmic functions, we can now solve basic logarithmic and exponential equations by rewriting. Example 4.2.3. Solve log 4 ( x) = 2 for x. By rewriting this expression as an exponential, 4 2 = x , so x = 16. Most calculators and computers will only evaluate logarithms of two bases.
