Number and Quantity: The Real Number System

Use properties of rational numbers and irrational numbers.

N.RN.1

Fully covered
(9/10) Know and apply the properties of integer exponents to generate equivalent numerical and algebraic expressions.

N.RN.2

Fully covered
(11) 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.
