Understanding Exponents: Definitions and Intuitions

The video tutorial explains the reasoning behind the definitions of zero and negative exponents. It starts by introducing the concept of negative exponents and their definition as 1 over the positive exponent. The tutorial then explores positive exponents, showing how multiplying by the base increases the exponent. It defines zero exponents by maintaining the pattern of dividing by the base, resulting in a value of one. The video further explains negative exponents by continuing this pattern, dividing by the base to achieve the negative exponent value. The tutorial concludes by emphasizing the consistency of exponent rules across different types of exponents.

Why is a to the negative b defined as 1 over a to the b?

• Because it simplifies calculations

• To make negative numbers positive

• To avoid using zero in calculations

• To maintain consistency with exponent rules
