- HSN-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. - HSN-RN.A.2 Rewrite expressions involving radicals and rational exponents using the properties of exponents.
