Pre-Calculus - Evaluating a Logarithm Using Condensing

The video tutorial explains how to evaluate logarithms with the same base using subtraction rules. It begins by introducing the problem of evaluating log base 5 of 75 minus log base 5 of 3. The instructor explains how to find the values for these logarithms by understanding the powers of 5. The tutorial then demonstrates how to apply the subtraction rule for logarithms, condensing the expression into a single logarithm. Finally, the instructor evaluates the simplified logarithm to find the solution.
