Exponent Calculator is a tool that computes the result of raising a base number to any power (exponent) — including negative exponents, fractional exponents (roots), and zero exponents — showing the step-by-step calculation.
How it works: It evaluates baseⁿ using JavaScript's Math.pow() function, which handles integer powers, negative exponents (1/baseⁿ), and fractional exponents (nth roots via base^(1/n)). For large integer bases and powers, it uses BigInt arithmetic to avoid floating-point precision loss.
When you need it: Users typically reach for Exponent Calculator when calculating compound interest growth (1.05^10), computing binary powers (2^8 = 256), evaluating scientific notation (10^−6 = 0.000001), finding the nth root of a number, or working through an algebra problem with exponents.
Key Facts
The fundamental exponent laws used in algebra and arithmetic.
| Rule | Formula | Example |
|---|---|---|
| Product rule | aᵐ × aⁿ = aᵐ⁺ⁿ | 2³ × 2⁴ = 2⁷ = 128 |
| Quotient rule | aᵐ ÷ aⁿ = aᵐ⁻ⁿ | 2⁵ ÷ 2² = 2³ = 8 |
| Power rule | (aᵐ)ⁿ = aᵐⁿ | (2³)² = 2⁶ = 64 |
| Zero exponent | a⁰ = 1 | 100⁰ = 1 |
| Negative exponent | a⁻ⁿ = 1 ÷ aⁿ | 2⁻³ = 1/8 = 0.125 |
| Fractional exponent | a^(m/n) = (ⁿ√a)ᵐ | 8^(2/3) = (∛8)² = 4 |
| Product to power | (ab)ⁿ = aⁿ × bⁿ | (2×3)² = 4×9 = 36 |
Exponentiation is right-associative: 2^3^2 means 2^(3^2) = 2^9 = 512, not (2^3)^2 = 64. Always use parentheses when the order is ambiguous.
