Bilangan berpangkat adalah perkalian yang berulang - ulang. Bilangan ini dikalikan sama dengan banyak pangkatnya. Bilangan berpangkat mempunyai nama lain yaitu Eksponen. Fungsi Bilangan Berpangkat adalah untuk menyederhanakan penulisan dan penyebut suatu bilangan.

ෆ Bentuk umum :

aⁿ = a × a × a × ... × a × a × a

{ a dikali sebanyak n }

ෆ Keterangan :

a = Baris

n = pangkat
