I am using numbers this time so you can convince yourself that the log law works.

LHS

`= log (20/5)`

`= log\ 4 `

`= 0.60206` (using calculator)

Now

RHS

`= log\ 20 − log\ 5`

`= 1.30103 − 0.69897` (using calculator)

`= 0.60206 `

= LHS

We have shown that the second logaritm law above works for our number example.
