Simplifying Expressions with Exponents

The video tutorial explains how to simplify expressions with negative exponents by using exponent rules. It emphasizes the importance of writing expressions with positive exponents and demonstrates how to apply these rules to move terms across the fraction bar, changing the sign of the exponent. The tutorial concludes with a simplified expression and a recap of the key concepts.

Why is the expression with X raised to the power of -3 not considered simplified?

• Because it has a negative exponent.

• Because it has a positive exponent.

• Because it is a fraction.

• Because it is an integer.
