About this calculator
Exponentiation: b^x means "b multiplied by itself x times" — but extends to fractional, negative, and zero exponents via b^x = e^(x·ln b). Special cases: b^0 = 1, b^(−x) = 1/b^x, b^(1/2) = √b, b^(1/n) = ⁿ√b. JavaScript Math.pow handles all cases. Note: 0^0 is conventionally 1 in combinatorics and discrete math; some calculators return NaN. Negative bases with non-integer exponents are typically NaN in real arithmetic.
