BILANGAN BERPANGKAT
By Syahruddin, S.Pd
2
PERPANGKATAN
Perpangkatan adalah perkalian berulang sebuah bilangan dengan bilangan itu sendiri
Perpangkatan dirumuskan dengan :
an = a x a x a x .... x a
(a dikalikan sebanyak n faktor)
Contoh :
72 dibaca tujuh pangkat dua sama artinya dengan 7 x 7
1. Pengertian perpangkatan
3
Contoh :
22 = 2 x 2 25 = 2 x 2 x 2 x 2 x 2
23 = 2 x 2 x 2 26 = 2 x 2 x 2 x 2 x 2 x 2
24 = 2 x 2 x 2 x 2 27 = 2 x 2 x 2 x 2 x 2 x 2 x 2
terbukti bahwa :
an = a x a x a x .... x a
(a dikalikan sebanyak n faktor)
2. Bilangan Bulat Pangkat Bilangan Bulat Positif
4
Contoh :
24 = 2 x 2 x 2 x 2= 16
23 = 2 x 2 x 2 = 8
22 = 2 x 2 =4
21 = 2
20 = 1
Secara umum dapat di rumuskan :
a0 = 1
4. Bilangan Bulat Pangkat Bilangan Nol
5
Contoh :
22 = 2 x 2 = 4 2-2 = 1/22= 1/4
23 = 2 x 2 x 2 = 8 2-3 = 1/23= 1/8
24 = 2 x 2 x 2 x 2 = 16 2-4 = 1/24= 1/16
Berdasarkan contoh diatas, kita dapat mengubah bilangan berpangkat negatif ke bilangan berpangkat positif dengan rumus :
a-n = 1/an
3. Bilangan Bulat Pangkat Bilangan Bulat Negatif
