Actions
Use this Exponent Calculator to calculate a number raised to a positive, negative, zero, or fractional power.
Calculation Method
The general expression is:
a = bx
Where b is the base, x is the exponent, and a is the result.
Common exponent rules include:
- Positive exponent: bn means repeated multiplication.
- Zero exponent: b0 = 1 when b ≠ 0.
- Negative exponent: b−n = 1 ÷ bn.
- Fractional exponent: bm/n = (ⁿ√b)m.
Example
Calculate:
2−3
2−3 = 1 ÷ 2³ = 1 ÷ 8 = 0.125
Important Note
Some expressions are undefined or do not have real-number results. Examples include 0 raised to a negative exponent and certain fractional powers of negative numbers.
