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. [NRN1]
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.
