Exploring Negative Exponents and Their Applications

Mr. Hood introduces the concept of expressing powers of 10 using negative exponents, fractions, and decimals. He explains that negative exponents represent values between 0 and 1, not negative numbers. The video provides examples of converting negative exponents into fractions and decimals, such as 10 to the negative first being 1/10 or 0.1. The lesson includes practice problems for viewers to try on their own.
