Calculate Powers & Exponents
Calculate any base raised to any power. Supports negative exponents, fractional exponents, and large numbers.
Les Puissances
aⁿ signifie a multiplié par lui-même n fois. 2⁵ = 2×2×2×2×2 = 32. Règles clés : a⁰ = 1. a¹ = a. a⁻ⁿ = 1/aⁿ. aᵐ × aⁿ = aᵐ⁺ⁿ. La croissance exponentielle double périodiquement — 2¹⁰ = 1 024, 2²⁰ = 1 048 576. L'intérêt composé suit la même logique.
Applications
Intérêts composés : P × (1+r)ⁿ. Croissance des populations. Échelle de Richter : chaque unité = 10× plus puissant. Informatique : 2¹⁰ = 1 Ko, 2²⁰ = 1 Mo, 2³⁰ = 1 Go.
The most practical exponent in everyday life: the Rule of 72. Divide 72 by the interest rate to estimate how many years it takes to double your money. At 8% return: 72÷8 = 9 years to double. This is compound interest (exponents) made simple enough for mental math.
