This document discusses logarithms and their properties. It explains the relationship between the base, exponent, and answer in a logarithmic expression. It provides examples of evaluating logarithmic expressions and converting between exponential and logarithmic form. It poses problems involving exponential and logarithmic functions, including comparing the intensities of two earthquakes using the Richter scale.
