About Exponent Calculator
Negative exponents
a^(−n) = 1 / aⁿ. So 2^(−3) = 1/8 = 0.125. Useful for very small numbers and for inverse operations.
Fractional exponents
a^(1/n) is the nth root of a. So 8^(1/3) = ∛8 = 2. More generally a^(m/n) = (n-th root of a)^m.
Special cases
a^0 = 1 for any a ≠ 0 (0^0 is conventionally 1 but undefined in some contexts). 1^anything = 1. 0^positive = 0. 0^negative = undefined.
