Negative Exponent Rule

The video tutorial reviews the negative exponent rule, addressing common misconceptions that negative exponents result in negative values. It presents a math question asking which expression is greater than zero, with four answer choices. The tutorial explains that a base raised to a negative exponent equals the reciprocal with a positive exponent. It eliminates answer choices A and B due to negative values and evaluates choices C and D, confirming C as the correct answer. The video concludes with a summary of interpreting negative exponents.
