Question

How do I find the value of `log 100`?

Answer 1

`log100=2`

Explanation:

One way we can approach log problems is to remember that

`a^b=c <=> log_ac=b`

In our question, since the value of `a` in the right hand side log isn't specifically listed, it's assumed to be 10. So what we have is:

`a^b=c <=> log_10(100)=b`

`10^b=100 <=> log_10(100)=b`

By observation of the left hand side, we can see that `b=2`
