    logarithmic functions and their graphs

    The problem: Choose 2 numbers and add their common logarithms. Then find the common logarithm of the product of those 2 numbers. What do you observe? Does it work for 3 numbers?

    What I know: common logarithms use base-10.

    What I think I know: a logarithm is an exponent.

    I don't know how to parlay my limited knowledge into a solution, please help

    I guess what they are after is that $\log(abc) = \log(a)+\log(b)+\log(c)$

    it's a standard property of logarithms
