Properties of Radicals and Fractional Exponents

Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents.

• By allowing for a notation for radicals in terms of rational exponents.

• By using only whole numbers.

• By ignoring the properties of integer exponents.

• By using only positive numbers.
