Zero and Negative Exponents
Name: _________________________
Date: _________________________
Remember: Any number to the power of 0 equals 1 (e.g. 5⁰ = 1). A negative exponent means "reciprocal" (e.g. 2⁻³ = 1/2³ = 1/8).
Part A: Zero Exponents
Evaluate each expression.
1. 7⁰ = ________________
2. 15⁰ = ________________
3. (-4)⁰ = ________________
4. 100⁰ = ________________
5. (1/2)⁰ = ________________
6. (-25)⁰ = ________________
Part B: Negative Exponents (Write as Fractions)
Rewrite each expression with a positive exponent, then evaluate.
7. 2⁻³ = ________________
8. 5⁻² = ________________
9. 3⁻¹ = ________________
10. 10⁻² = ________________
11. 4⁻² = ________________
12. 2⁻⁵ = ________________
Part C: Negative Exponents (Write as Decimals)
Evaluate each expression and write your answer as a decimal.
13. 10⁻¹ = ________________
14. 10⁻³ = ________________
15. 5⁻¹ = ________________
16. 2⁻⁴ = ________________
Part D: Mixed Practice
Evaluate each expression. Write answers as fractions or whole numbers.
17. 8⁰ + 2⁻² = ________________
18. 3⁻³ = ________________
19. 6⁻¹ × 6¹ = ________________
20. (2⁻¹)² = ________________
21. 4⁰ × 4⁻¹ = ________________
22. 10⁻⁴ = ________________
