Regeln
a^n = a mal sich selbst n-mal. 2^5 = 32. a^0 = 1. a^(-n) = 1/a^n. a^m × a^n = a^(m+n). Zinseszins folgt derselben Logik: K × (1+r)^n.
Anwendungen
Zinseszins. Bevoelkerungswachstum. Richter-Skala: jede Stufe = 10× staerker.
⚡ 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
Warum a^0 = 1?▾
Kontinuitaet: a^3/a = a^2, a^2/a = a^1, a^1/a = a^0 = 1.
Negativer Exponent?▾
a^(-n) = 1/a^n. 2^(-3) = 1/8 = 0,125.
