IB MATEMATICS Topic ; Logarithms – Simplifying Logarithmic Expressions

It will first be relevant to summarise the rules of logarithms:

(1)
(2)
(3)
(4)
(5)
Often we can simplify a logarithmic expression so that it becomes either a single log, or a constant plus a log.
Example: Simplify
using (1)
using (3)
using (5)
Example: Ifexpressterms of p
