In this video tutorial, Miss Smith explains two key laws of exponents: the negative exponent rule and the dividing exponents rule. She provides clear examples to illustrate each rule, emphasizing the importance of converting negative exponents to positive ones and subtracting exponents when dividing. The tutorial aims to simplify these concepts for better understanding and application in math problems.
