    If base ten, then what is the exponent on 10 that would make the power = 0.001?

    You know you can rewrite 0.001 as an exponent right?

    0.001 = 1/1000, what is 1000 as a power of ten?

    10^3

    Great, but since it is in the denominator, 1/1000 = 10^-3.

    Does that make sense?

    yes. so if you have log w/ 1/1000 how do you evaluate that ?

    I will reask my first question: "what is the exponent on 10 that would make the power = 0.001?"

    Yeah but exponets and logarithms are exponents of each other.

    Logarithms *are* exponents.

    The logarithm tells you (or asks you, if a variable is involved) what the exponent is.

    So as @CliffSedge said 0.001 is the same as 10^ -3 .

    Do you know your logarithm properties?
