a^b multiplies a by itself b times (for integer b). For fractional b, it represents roots (e.g., a^(1/2) = √a).a^m · a^n = a^(m+n), (a^m)^n = a^(m·n), a^0 = 1 (if a ≠ 0), a^-n = 1 / a^n.a^(p/q) = q√(a^p). Requires a ≥ 0 in real numbers when q is even.0^0 and 0 to a negative exponent are undefined in this tool.1/3 for exact cube roots (e.g., 27^(1/3) = 3).INF; tiny results may underflow to 0.Choose which optional categories you allow.
