Understanding Exponential Notation Concepts

This video tutorial teaches how to compare numbers written in exponential notation by understanding place value. It reviews the powers of 10, explaining how exponents indicate the number of times the base 10 is used as a factor. The tutorial provides examples comparing numbers with different exponents, demonstrating how to shift digits and fill empty spaces with zeros to understand the magnitude difference. The lesson concludes by emphasizing the importance of comparing exponents when whole numbers and decimals are equal.
