Simplifying Expressions with Negative Exponents

This lesson teaches how to simplify expressions with negative exponents by applying known exponent rules. It explains that a base raised to a negative exponent moves to the opposite position (numerator or denominator) with a positive exponent. The video provides examples, such as simplifying 1 divided by 5 to the negative third and expressions with variables, illustrating the process of moving exponents and simplifying fractions.
