Log Rules:
1)
2)
3) ...you need to apply this rule
..simplified using base
now you can change the base if you will:
In order to evaluate a non-standard-base log, you have to use the Change-of-Base formula:
usually we use base
so, you will have
your teacher shows this simplifying to which is wrong
is equal (using the rule from above, but given
is =>is equal to not only
