Exponent Calculator — Calculate Powers & Exponents Easily

Exponent Calculator

Calculate any base raised to a power (x^y). Visualize exponential growth, compare powers, and understand exponent rules with our free interactive tool.

Step 1: Base & Exponent

Understanding Exponents

An exponent tells how many times to multiply the base by itself. Example: 2³ = 2 × 2 × 2 = 8. Negative exponents mean reciprocal: 2⁻³ = 1/(2³) = 0.125.

Step 2: Display Options

About precision

Adjust decimal places or switch to scientific notation for very large (e.g., 10^25) or very small numbers.

Exponent rules

x^a · x^b = x^(a+b)   |   (x^a)^b = x^(a·b)

For any non‑zero base: x⁻ⁿ = 1/xⁿ. x^(m/n) = ⁿ√(xᵐ). Our calculator handles real exponents using JavaScript’s Math.pow.
