1.14 Negative Exponents

  • Negative exponents are a way of indicating reciprocals.
  • Negative exponent is equivalent to the inverse of the same number with a positive exponent.
    Example:
    2-3 = 1/23 = 1/8
Other examples:
3-2 = 1/32 = 1/9 (-2)2 = (-2) x (-2) = 4
6-2 = 1/62 = 1/36 -22 = - (2 x 2 ) = -4
2-4 = 1/24 = 1/16 (-2)3 = (-2) x (-2) x (-2) = -8
5-1 = 1/51 = 1/5 -23 = - ( 2 x 2 x 2) = - 8
1/2-2 = 22 = 4 (-2)-2 = 1/(-2)2 = 1/(-2x-2) = 1/4
