aⁿ.
Computes a^n for real base and exponent.
Negative exponents are reciprocals (a^-n = 1/a^n); fractional exponents are roots (a^(1/n) = ⁿ√a).
Exponents grow numbers far faster than multiplication once the base is above 1, which is the core reason compound interest, population growth, and viral spread all eventually outpace naive linear predictions.
2^10 = 1024.
Conventionally 1 in combinatorics and computing (and this tool). Sometimes left undefined in pure math.
Result may overflow to Infinity (>~1.8 × 10^308 in double precision).
Split it into a root and a power: take the cube root of 8 (which is 2), then square that result, giving 4.
