The video tutorial covers solving logarithmic equations. It begins with a review of guidelines for solving log equations, including combining logs, isolating the log, converting to exponential form, solving for the variable, and checking the answer. Two examples are provided: one involving a natural log equation and another with a common log equation. Each example demonstrates the process of solving the equation and verifying the solution.
