(B) Simplify numeric and algebraic expressions using the laws of exponents, including integral and rational exponents.
(Y9) Extend and apply the index laws to variables, using positive integer indices and the zero index (ACMNA212)
8.EE.1 Know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 32 × 3-5 = 3-3 = 1/33 = 1/27.HSA.APR.1
HSA.APR.1 Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.
