Understanding Negative Exponents

The video tutorial explains how to handle negative exponents by moving them and their bases to the denominator, changing the exponent to positive, and placing a one in the numerator if needed. Several examples are provided, including calculations with numbers and variables, demonstrating the simplification process.

What should you do with a negative exponent in a fraction?

• Ignore it.

• Move it to the numerator and make it positive.

• Move it to the denominator and make it positive.

• Leave it as it is.
