About the exponent calculator
Raising a number to a power means multiplying the number (the base) by itself as many times as the exponent indicates. For example, 2 to the power of 3 is 2 × 2 × 2 = 8.
This calculator handles more than whole-number exponents — it also supports fractional and negative powers, where a fractional exponent is a root and a negative exponent is a reciprocal.
All calculations run instantly right in your browser — the numbers you enter are never uploaded or stored, keeping the computation fully local and private.

Frequently asked questions
How do I raise a number to a power?
Multiply the base by itself as many times as the exponent says. For example, 5 to the power of 2 is 5 × 5 = 25. Just enter both values into the calculator.
What is the zero exponent?
Any nonzero number raised to the power of 0 equals 1. This follows from the rules for dividing powers that share the same base.
What does a negative exponent mean?
A negative exponent gives the reciprocal: a number to the power of −n equals 1 divided by that number to the power of n. For example, 2 to the power of −2 equals 1/4.
Can I use a fractional exponent?
Yes. A fractional exponent corresponds to a root — for instance, a number to the power of 0.5 is its square root.
Is my data saved?
No. All calculations happen locally in your browser, so your numbers are never sent to a server or stored.
