An exponent tells you how many times to multiply a base by itself — and the rule extends naturally to negative and fractional exponents too.
This calculator raises any base to any exponent, positive, negative, or fractional.
How it works
Enter a base and an exponent. The calculator raises the base to the given power using the general power rule, which covers whole-number, negative, and fractional exponents alike.
- Enter base.
- Enter exponent.
- Click Calculate to see your results.
Examples
A whole-number exponent
2 raised to the 10th power is 1,024.
A fractional exponent
9 raised to the power of 0.5 is 3 — a fractional exponent of 0.5 is the same as a square root.
Who should use it
- Checking algebra or pre-calculus homework involving exponents.
- Calculating compound growth or decay factors that involve fractional powers.
Industry applications
- Mathematics and science education
- Engineering and financial calculations involving exponential growth
Advantages
- Supports whole-number, negative, and fractional exponents in one tool.
- Flags results that are too large to calculate rather than returning an incorrect value.
Limitations
- Very large bases combined with large exponents may exceed calculable limits.
Common mistakes to avoid
- Confusing a negative exponent with a negative result — base^(-n) is a reciprocal, not a negative number (unless the base itself is negative).
- Forgetting that any nonzero number raised to the power of 0 equals 1.
Best practices
- When working with fractional exponents, remember the denominator of the fraction indicates the root (square root, cube root, etc.) and the numerator indicates the power.
Tips
- To find a root of a number using this calculator, use a fractional exponent — for example, a cube root is the same as raising to the power of 1/3 (about 0.3333).
