Introduktion til potenser

Eksponenter repræsenterer gentagen multiplikation, og de gør hurtigt et tal meget stort. For eksempel er 2 opløftet til 3 potens det samme som 2 gange 2 gange 2, hvilket er 8. Potenser er altså anderledes en multiplikation, som svarer til gentagen addition. Det er vigtigt at lære at bruge potenser, inden du kommer til matematik på højere niveau. Lavet af Sal Khan.
