Integer Exponents





 

Videos and lessons to help Grade 8 students know and apply the properties of integer exponents to generate equivalent numerical expressions.
For example, 32 × 3–5 = 3–3 = 1/33 = 1/27.

Common Core: 8.EE.1

Suggested Learning Targets


  • I can explain why a zero exponent produces a value of one.
  • I can explain how a number raised to an exponent of -1 is the reciprocal of that
    number.
  • I can explain the properties of integer exponents to generate equivalent numerical
    expressions.

    1. Multiplying Exponents of the same base
    For example, 32 x 3-5 = 1/33 = 1/27

    2. Dividing Exponents of the same base
    For example, 32/ 3-1 = 1/33 = 1/27

    3. Expand an exponent by another exponent
    For example (22)3 = 64
