Exponent Calculator
Any base to any power, including negative and fractional exponents.
Exponent rules worth remembering
A negative exponent is a reciprocal: 2⁻³ = 1/8. A fractional exponent is a root: x^(1/2) is the square root, x^(1/3) the cube root, and x^(2/3) is 'cube root, then square'. Anything to the power 0 is 1. Multiplying same-base powers adds exponents; raising a power to a power multiplies them.
Negative bases
(-2)³ = -8 and (-2)⁴ = 16: odd exponents keep the sign, even ones erase it. Fractional powers of negative numbers leave the real number line entirely, which is why the calculator refuses them rather than inventing an answer.
