🔢 Exponent Calculator
Enter a base number and an exponent to instantly calculate the result of base raised to that power.
What this calculator does
This tool raises a base number to a given exponent (power), handling whole numbers, decimals, and negative exponents. It is useful for algebra homework, science calculations, and quick checks of exponent rules.
The formula used
The result is simply baseexponent, calculated as base multiplied by itself "exponent" times for positive whole exponents. A negative exponent gives the reciprocal (for example, 2-3 = 1 ÷ 2³ = 0.125), and a fractional exponent corresponds to a root (for example, 90.5 is the square root of 9).
Good to know
Some combinations, such as a negative base with a non-integer exponent, do not have a real-number result; this calculator returns 0 in those edge cases rather than an error. This tool is intended for general educational and homework use.
