Exponents and Their Properties

Mrs. Lopez introduces the concept of exponents as repeated multiplication and demonstrates how to multiply numbers in exponential notation. She provides examples, explains the general rule for multiplying exponents with the same base, and guides students through exercises. The lesson concludes with a preview of the next topic: dividing numbers in exponential form.
