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.

What is the exponent on the number two in the expression?

• Zero

• Negative one

• One

• Two

What does the exponent rule state about moving an exponent across the fraction bar?

• It squares the base.

• It changes the sign of the exponent.

• It doubles the exponent.

• It halves the base.

How do you write a negative exponent as a positive exponent using the fraction method?

• By moving the base to the denominator.

• By moving the base to the numerator.

• By adding one to the exponent.

• By subtracting one from the exponent.

What happens to the exponent of X when it is moved to the denominator?

• It becomes negative.

• It becomes positive.

• It becomes zero.

• It remains the same.

Where does the number two remain in the simplified expression?

• Outside the fraction

• In the numerator

• In the denominator

• In the exponent

What is the final form of the expression after simplification?

• 2/X^3

• X^3/2

• 2X^3

• X/2^3
