Exponent Rules and Simplification

The video tutorial covers simplifying expressions with negative exponents. It begins with an introduction to the concept and then demonstrates two examples. The first example shows a detailed step-by-step process of simplifying a complex expression using basic exponent rules. The second example introduces an alternative method for simplification, emphasizing the importance of handling negative exponents correctly. The tutorial aims to make exponents positive and simplify the expressions by applying multiplication and subtraction rules.
