Expressing Powers of 10 with Exponents

Mrs. Smith introduces exponents and powers of 10, focusing on how exponents indicate the number of times a base number is multiplied by itself. The video explains powers of 10, showing how to express them using exponents and identifying patterns in the number of zeros. Students learn to apply this knowledge in calculations, such as multiplying numbers by powers of 10. The video concludes with encouragement to continue learning and subscribing for more content.
