Question

Simplyfy `ln(1/90)` in terms of ln?

Answer 1

`-[color(white)(.)2ln(3)+ln(2)+ln(5)color(white)(.)]`

Explanation:

This is the same as `ln(1)-ln(90)`

but `ln(1)=0` so we only need to consider `-ln(90)`

Lets consider `90->3xx30=3xx3xx10 = 3xx3xx2xx5`

So we have:

`-[color(white)(.)2ln(3)+ln(2)+ln(5)color(white)(.)]`
