EXTEND THE PROPERTIES OF EXPONENTS TO RATIONAL EXPONENTS.

• A2:N-RN.A.1 Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. For example, we define 5^(1/3) to be the cube root of 5 because we want (5^(1/3))^3 = 5(^(1/3))^3 to hold, so (5^(1/3))^3 must equal 5.
• A2:N-RN.A.2 Rewrite expressions involving radicals and rational exponents using the properties of exponents.
