Exponent Calculator
Calculate base raised to a power (exponentiation). Enter the base and exponent to get the result. Supports negative exponents, which give the reciprocal. Useful for scientific notation, growth calculations, and math.

What is this?
Exponentiation (base^exponent) means multiplying the base by itself exponent times. For example, 2^3 = 2 × 2 × 2 = 8. A negative exponent gives the reciprocal: 2^(-2) = 1/4. Zero as exponent gives 1 (except 0^0 which is undefined). The calculator supports both positive and negative exponents, and handles decimal bases and exponents. Large exponents can produce very large or very small results. Exponentiation is fundamental to compound growth, decay, and many scientific formulas.
When to use
Use for compound growth, scientific notation, probability, or any power calculation. Example: 1.05^10 ≈ 1.63 (5% growth for 10 periods). 2^(-3) = 1/8. Financial analysts model growth with exponents. Scientists work with powers of 10. Programmers verify bit shifts (2^n). Students solve algebra and calculus problems. Anyone needing to raise a number to a power will find this faster than repeated multiplication.
How to use
Enter base and exponent. Result = base^exponent. Supports negative exponents (gives reciprocal).
Frequently asked questions
- A negative exponent means take the reciprocal. For example, 2^(-3) = 1/(2^3) = 1/8.
- 0^0 is mathematically undefined. This calculator may return 1 in some implementations, but it is a special case.
