#### MAT-HS.N-RN.01

 MAT-HS Targeted Standards(N) Concept: Number and Quantity(RN) Domain: The Real Number SystemCluster: Extend the properties of exponents to rational numbers MAT-HS.N-RN.01 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.
