Solving Exponential Equations Without a Calculator

The video tutorial explains how to solve exponential equations using the one-to-one property. It begins with an introduction to the concept, followed by basic examples that do not require a calculator. The tutorial then covers handling negative exponents and fractions, applying exponent rules, and solving more complex equations with expressions as exponents. The instructor emphasizes the importance of rewriting bases to be the same and using the power rule to simplify equations.

What does the one-to-one property state?

• If a^x = a^y, then x = y

• If a^x = b^y, then x = y

• If a^x = b^y, then x = y + 1

• If a^x = a^y, then x = y + 1
