Comparing Small Numbers Using Scientific Notation

The video tutorial explains how to compare very small numbers using scientific notation. It begins by introducing a problem involving the size comparison between a period on a page and a bacterium. The lesson covers how to write small numbers in scientific notation, emphasizing the placement of the decimal point and the importance of the power of ten. It also reviews the properties of exponents, including how to add them when multiplying powers. Finally, the tutorial solves the problem by estimating the size difference using scientific notation, concluding that the period is about 300 times larger than the bacterium.
