Grade
Grade 9
Concept/Content
exponents and exponent laws with whole-number exponents
Elaboration
  • includes variable bases
  • 27 = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128; n4 = n x n x n x n
  • exponent laws (e.g., 60 = 1; m1 = m; n5 x n3  = n8; y7/y3 = y4; (5n)3 = 53 x n3 = 125n3; (m/n)5 = m5/n5; and (32)4 = 38)
  • limited to whole-number exponents and whole-number exponent outcomes when simplified
  • (–3)2 does not equal –32
  • 3x(x – 4) = 3x2 – 12x
