Perkalian Bilangan Bulat
PERKALIAN BILANGAN BULAT
Perkalian adalah penjumlahan yang berulang. contoh 15 + 15 + 15 + 15 = 4 x 15 = 60
rumus perkalian Bilangan Bulat:
+ x + = +
+ x - = -
- x + = -
- x - = +
contoh
1. 6 x 5 = 30
2. -3 x 2 = -6
3. 5 x (-7) = -35
4. -2 x (-3) = 6

Menghitung operasi bilangan suatu bilangan pangkat
Pangkat dari bilangan yaitu perkalian bilangan tersebut sebanyak pangkatnya.
Contoh
a² = a × a
2² = 2 × 2 = 4
3² = 3 × 3 = 9
6
Contoh tabel pangkat dua
Contoh Soal
Hasil ( 13 + 16 )² + 28² = ....
= ( 13 + 16 )² + 28²
= 29² + 28²
= 841 + 784
= 1.625
7
Menentukan perhitungan bilangan perpangkatan tiga
Pangkat dari bilangan yaitu perkalian bilangan tersebut sebanyak pangkatnya.
Contoh
a³ = a × a × a
2³ = 2 × 2 × 2 = 8
3³ = 3 × 3 × 3 = 27
