Understanding Negative Exponents

The video tutorial explains how to handle negative exponents by visualizing them as being on the wrong floor, requiring a switch between the numerator and denominator. It covers simplifying expressions with both negative and positive exponents, including those involving variables. The tutorial provides multiple methods for handling negative exponents in fractions, emphasizing the importance of understanding exponent rules and simplification techniques.

What does a negative exponent indicate about the position of a term in a fraction?

• It is on the correct floor.

• It is on the wrong floor.

• It should be squared.

• It should be cubed.
