Dividing Logs worked examples Simplify $$\frac{\log16}{\log8}$$.  $$=\frac{\log2^4}{\log2^3}$$ there is no log law to allow us to directly divide logs, so we are going to rewrite them with the same numbers as powers consider what both 16 and 8 can be written to the power of 16 = 24 and [...]

Change Of Base $$\log_ab=\frac{\log a}{\log b}$$ worked examples Change to log base 10: log3 6 and calculate to 4 decimal places. $$\log_36=\frac{\log 6}{\log 3}$$ it is convenient for calculating to have the log in base 10, as that is the log button on a calculator. By using the change [...]

Mixed Log Laws

Mixed Log Laws worked examples Simplify 4log 2 + log 3.  = log 24 + log 3 since alog b = log ba, we rewrite the 4log 2 as log 24 = log (16 × 3) 24 = 16 and the log law for addition is log a + [...]
