Exponent Calculator
Compute b raised to e in the supported real-number model. Positive bases accept decimal exponents; negative bases require an integer exponent. For a real odd root of a negative number, use the Root Calculator with an integer root degree. Zero to a negative power is rejected; this tool follows the JavaScript convention 0^0 = 1.
From your base and exponent, Exponent Calculator computes the result via the standard method. No accounts, no uploads — just an instant way to work through a calculation.

FAQ
What does the Exponent Calculator do?
It raises a base to a power — for example 2 to the 10th power equals 1024.
Can the exponent be negative or a fraction?
Negative exponents give reciprocals when the base is nonzero. Fractional exponents are supported for nonnegative bases, except zero with a negative exponent. Negative-base fractional inputs require a separate real-root interpretation and are rejected here.
What do I enter in the Exponent Calculator?
A base and an exponent; the calculator returns base raised to that exponent.
Does the Exponent Calculator send my data to a server?
No — the Exponent Calculator runs entirely in your browser, so the numbers you enter never leave your device.
Worked example
Evaluate 210 = 2 multiplied by itself ten times = 1024.
