Evaluating a Logarithm with Base 10

The teacher begins by apologizing for not covering a topic in the previous class. The lesson focuses on understanding logarithms, particularly when no base is specified, assuming it to be base 10. The teacher explains how to evaluate logarithms by rewriting them in exponential form. An example problem is solved using the one-to-one property, demonstrating how to equate exponents with the same base to find the value of a variable.
