Calculate any base raised to any power — including large exponents, negative exponents, and fractional (decimal) exponents.
An Exponent Calculator computes the result of raising a base number to a power, meaning how many times the base is multiplied by itself.
Result equals Base raised to the Exponent. Special cases include any number to the power of zero equaling 1, negative exponents producing fractions, and fractional exponents representing roots.
Enter the base number. Enter the exponent, which can be positive, negative, zero, or a decimal. Click Calculate to see the result instantly.
Example 1: 5 to the power of 3 equals 5 times 5 times 5, which is 125.
Example 2: 2 to the power of negative 3 equals 1 divided by 8, which is 0.125.
Example 3: 16 to the power of 0.5 equals the square root of 16, which is 4.
Calculating compound interest growth over periods. Scientific notation for very large or small measurements. Computer science storage size calculations. Population growth modeling in biology.
What does a negative exponent mean. It means taking the reciprocal of the base raised to the positive exponent.
What happens with fractional exponents. They represent roots, an exponent of one half is a square root.
Can the base be negative. Yes, the result depends on whether the exponent is even or odd.
Why does anything to the power of zero equal one. This follows from consistent exponent division rules.
Is there a limit to exponent size. Very large exponents may show results in scientific notation but are handled correctly.
