Hey Guys,

Wracking my brain trying to understand the math behind this log question. Highlited in red in the link below.

Could someone please explain why this step is being divided?

Thank you!

You are looking at a worked solution that is not related to the real GAMSAT: ACER has 440 Section 3 MCQs with heaps of logs but they never use that obscure rule.

But if you are interested, the log change of base rule allows the conversion to division.
