Solving Negative Exponents: Key Concepts and Examples

This video tutorial by Mr. J explains how to solve negative exponents through six examples. It covers the concept of changing negative exponents to their reciprocals, keeping the base unchanged, and converting the exponent to positive. Each example demonstrates the step-by-step process of solving negative exponents, emphasizing the difference between positive and negative exponents and their effects on the base value.

What does a negative exponent indicate?

• A negative result

• An increase in value

• A positive result

• A reciprocal of the base raised to the positive exponent
