Understand that the denominator of the rational exponent is the root index and the numerator is the exponent of the radicand (e.g., 51/2 = √5). Extend the properties of exponents to justify that (51/2)2=5
Clarifications:

Essential Understandings

  • Understand how to multiply fractions and whole numbers.
  • Understand that a fractional exponent is a root.
  • Understand that a root is the inverse of a fractional exponent.
  • Understand that “radicals” (roots) are the “opposite” operation of applying exponents.
  • Understand that you can “undo” a power with a radical, and a radical can “undo” a power.

Date Adopted or Revised: 07/14
Cluster: Extend the properties of exponents to rational exponents. (Algebra 1 - Major Cluster) (Algebra 2 - Major Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
