Extend the properties of exponents to rational exponents

HSN.RN.A.1

Fully covered
Explain how extending the properties of integer exponents to rational exponents provides an alternative notation for radicals. For example: We define 5^(4/3) to be the cube root of 5^4 because we want (5^(4/3))^(3/4) = 5 to hold.

Use properties of rational and irrational numbers

HSN.RN.B.4

Mostly covered
Simplify radical expressions. Perform operations (add, subtract, multiply, and divide) with radical expressions. Rationalize denominators and/or numerators
