Evaluate powers with any integer exponent

Grade 8 math · Fieldbook Learning

Name ______________________ Date __________

Multiply the base by itself as many times as the exponent says. A zero exponent gives 1, and a negative exponent means take the reciprocal.

  1. Evaluate 6⁻⁴. (Write a whole number or a fraction.)
  2. Evaluate (−8)³. (Write a whole number or a fraction.)
  3. Evaluate 5⁻⁴. (Write a whole number or a fraction.)
  4. Evaluate 3⁵. (Write a whole number or a fraction.)
  5. Evaluate (−5)⁵. (Write a whole number or a fraction.)
  6. Evaluate 5². (Write a whole number or a fraction.)
  7. Evaluate (−10)³. (Write a whole number or a fraction.)
  8. Evaluate (−12)⁰. (Write a whole number or a fraction.)
  9. Evaluate (−13)⁻³. (Write a whole number or a fraction.)
  10. Evaluate 2⁻⁴. (Write a whole number or a fraction.)
  11. Evaluate (−9)⁻². (Write a whole number or a fraction.)
  12. Evaluate (−10)⁻³. (Write a whole number or a fraction.)
