Solving Exponential Equations Techniques

This video tutorial focuses on solving exponential equations by expressing both sides with a common base, avoiding the use of logarithms. It provides multiple examples, demonstrating how to rewrite equations to have the same base and solve for the variable by equating exponents. The video covers equations with bases 2, 3, and 5, including a quadratic equation example. The next video will explore solving these equations using logarithms.
