log_(5)5=1

Explanation:

When we write log_(x)y=z, we ask to what power we raise the base x to get y; here if log_(x)y=z, then x^(z)=y. I can use any base, but typically scientists assume natural logarithms, log_e, if the base is not specified, or, more rarely, log_10.

Given this, can you tell me log_(10)100, log_(10)1000, and log_(10)0.01? These are all simple whole numbers.
