WebJust use this formula: "x goes up, a goes down" 1log b a works as a "conversion factor" from one base to any other base. Another useful property is: log a x = 1 / log x a. See how "x" and "a" swap positions? Example: Calculate 1 / log 8 2. 1 / log 8 2 = log 2 8. And 2 × 2 × 2 = 8, so when 2 is used 3 times in a multiplication we get 8: Weblog 2 ( x) + log 2 ( x − 2) = 3 log 2 [ ( x ) ( x − 2)] = 3 log 2 ( x2 − 2 x) = 3 Now the equation is arranged in a useful way. At this point, I can use The Relationship to convert the log form of the equation to the corresponding exponential form, and then I can solve the result: log 2 ( x2 − 2 x) = 3 2 3 = x2 − 2 x 8 = x2 − 2 x 0 = x2 − 2 x − 8
