Worksheet: Logarithmic Function

Solutions to Problems 25 Problem 1. Let m= log a M;so M= am:Then Mk= (am)k= amk= akm; where we have used the appropriate rule for indices. From this we have, by the de nition of a logarithm, km= log a Mk: But m= log a M;so the last equation can be written klog a M= km= log a Mk; which is the result we wanted.

Laws of Logs. The properties of indices can be used to show that the following rules for logarithms hold: log a x + log a y = log a (xy) log a x – log a y = log a (x/y) log a x n = nlog a x. Example. Simplify: log 2 + 2log 3 - log 6 = log 2 + log 3² - log 6 = log 2 + log 9 - log 6 = log (2 × 9) - log 6 = log 18 - log 6 = log (18/6) = log 3. NB: In the above example, I have not written what ...
