Comparing Numbers in Exponential Notation

This video tutorial teaches how to compare numbers written in exponential notation by understanding place value. It reviews powers of 10, explaining how exponents indicate the number of times 10 is used as a factor. The tutorial compares numbers like 3.2 x 10^4 and 3.2 x 10^5, showing how to determine which is greater by examining exponents and shifting decimals. It also compares 1.4 x 10^3 and 1.4 x 10^4, reinforcing the concept that a higher exponent results in a larger number. The lesson concludes by emphasizing the importance of comparing exponents when whole numbers and decimals are equal.
