log_10(0.01)=-2

Explanation:

Given that we have to find the value of log_10(0.01)

Now, I believe you're familiar with exponents, powers and bases and about the number system being based on the powers of 10.
So you'd obviously we can write that 0.01 is the same as 10^-2

So writing that instead of 0.01, we get that the problem is a bit easier, log_10(10^-2)
Now, i'm sure you know a good amount of logarithms too, so you must know that log_nm^l=llog_nm and that log_n(n)=1 which means that for our problem up there is now very simple.

So, that means, in the end, log_10(0.01)=-2log_10(10)

You know what to do next.
