Question

What is the logarithm of `100` divided by `25` ?

Answer 1

`log(100/25) = 2log(2) ~~ 0.60206`

`log(100)/25 = 2/25 = 0.08`

Explanation:

A good approximation is:

`log(2) ~~ 0.30103`

So we find:

`log(100/25) = log(4) = log(2*2) = 2log(2) ~~ 0.60206`

If instead you intended `log(100)/25` then we find:

`log(100)/25 = log(10^2)/25 = 2/25 = 8/100 = 0.08`
