Exponents and Their Properties

The video tutorial explains the rules of exponents in numerical expressions with rational exponents. It covers how to multiply and divide exponents with the same base, the concept of zero and negative exponents, and how to handle fractional exponents. The tutorial provides examples to illustrate each concept, such as adding exponents when multiplying the same base, subtracting exponents when dividing, and converting negative exponents into fractions. It also explains how fractional exponents relate to roots and powers, providing a comprehensive understanding of exponent rules.
