Exponent Calculator
Loading Power Core...
How it Works
01Enter the Base
Input the base number — the value that will be raised to a power. The calculator accepts positive numbers, negative numbers, and decimals as the base.
02Enter the Exponent
Input the exponent (power). Supports positive integers, negative exponents (reciprocals), and fractional exponents (roots) like 0.5 for square root.
03Handle Negative & Fractional Powers
Negative exponents compute the reciprocal (b⁻ⁿ = 1/bⁿ). Fractional exponents compute roots (b^(1/n) = ⁿ√b). Both are handled automatically.
04Get the Exact Power Result
The calculator outputs the result of bⁿ with full decimal precision. Large values are displayed in scientific notation for readability.

How It Works?
The formula
Negative exponent: b⁻ⁿ = 1 / bⁿ
Fractional exponent: b^(p/q) = qth root of bᵖ = (ᵍ√b)ᵖ
Zero exponent: b⁰ = 1 (for any b ≠ 0)
Calculation In Practice
3⁻² = 1/9 ≈ 0.1111
27^(1/3) = ∛27 = 3
5⁰ = 1
Scientific notation: 6.02 × 10²³ = 602,000,000,000,000,000,000,000
