Enter a base and exponent to see the result.

0^0 is conventionally defined as 1, though it is technically indeterminate.

0 raised to a negative exponent is undefined (division by zero).

xᵃ × xᵇ = xᵃ⁺ᵇMultiplying same base: add exponents

(xᵃ)ᵇ = xᵃᵇPower of a power: multiply exponents

xᵃ / xᵇ = xᵃ⁻ᵇDividing same base: subtract exponents

(xy)ᵃ = xᵃ × yᵃPower of a product: distribute the exponent

x⁰ = 1Any non-zero number to the power of 0 is 1

x⁻ⁿ = 1 / xⁿNegative exponent: take the reciprocal

How to use

1

Enter the base

Type the base number (x) into the first field.
2

Enter the exponent

Type the exponent (n) into the second field. Use decimals for fractional exponents.

Read the result

The result x^n appears instantly in both standard and scientific notation.

What is a negative exponent?

A negative exponent means the reciprocal: x^(-n) = 1/x^n. For example, 2^(-3) = 1/8.

What is a fractional exponent?

A fractional exponent represents a root: x^(1/n) = the nth root of x. For example, 8^(1/3) = 2.

What is 0 to the power of 0?

By convention, 0^0 = 1 in most contexts, though it is technically indeterminate.

Compute any power or exponent. Enter a base and exponent to get the

result, including negative exponents (reciprocals), fractional exponents

(roots), and zero exponent. Results are shown in standard and scientific

notation for very large or small values. A collapsible reference card

lists the key power rules. All processing runs in your browser.
