As Potências
aⁿ = a multiplicado por si mesmo n vezes. 2⁵ = 32. Regras: a⁰ = 1. a⁻ⁿ = 1/aⁿ. aᵐ × aⁿ = aᵐ⁺ⁿ. Juros compostos seguem a mesma lógica: P × (1+r)ⁿ.
Aplicações
Juros compostos. Crescimento populacional. Escala Richter: cada unidade = 10× mais forte. Informática: 2¹⁰ = 1 KB.
⚡ CalcWolf Insight
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.
Frequently asked questions
Por que a⁰ = 1?▾
Continuidade: a³÷a = a², a²÷a = a¹, a¹÷a = a⁰ = 1.
Expoente negativo?▾
a⁻ⁿ = 1/aⁿ. 2⁻³ = 1/8 = 0,125.
