Learn how to simplify by rewriting an exponent with a positive power

This video tutorial explains how to simplify expressions using the properties of exponents, focusing on converting negative exponents to positive by rewriting them in the denominator. The instructor provides a step-by-step example, demonstrating the simplification process and concluding with a summary of the rules of exponents.

What is the main focus when simplifying expressions using properties of exponents?

• Eliminating all variables

• Removing negative exponents

• Changing the base of exponents

• Increasing the power of exponents

How can you make a negative exponent positive?

• By adding 1 to the exponent

• By rewriting it in the numerator

• By rewriting it in the denominator

• By multiplying it by zero

What happens to the expression 2 * 1 / y when y has a negative exponent?

• It becomes 2 * y^3

• It remains unchanged

• It becomes 2 / y^3

• It becomes 2 * y

What is the result of multiplying across the fraction 2 * 1 / y^3?

• 1 / y^3

• 2 / y^3

• 2 * y^3

• 2 * y

What is the final expression after simplifying 2 * 1 / y with y to the negative third?

• 2 * y

• 2 * y^3

• 2 / y^3

• 1 / y^3
