Negative Exponents and Operations with Scientific Notation

This video tutorial covers the concept of negative exponents and their application in scientific notation. It explains how to solve problems involving exponents, identify errors, and simplify expressions. The tutorial also explores the relationship between negative exponents and fractions, and demonstrates how to perform operations using scientific notation. Through examples, it illustrates the use of exponents in both large and small scale measurements, such as in astronomy and microscopy.
