Re: How would you work this out on a calculator or step by step

Here is the step by step.

For any two numbers a and b, if a = b, then ln(a) = ln(b).

So since:

It must be that:

Also, for any two numbers a and b:

So it must be that:

Thus, dividing both by ln(3), we get:

Plug this fraction into a calculator, and you get n.
