berapa kali berapa hasilnya ( -8 )

Jawaban 2

Jawab:-4 × 2 = -84 × (-2) = -8-8 × 1 = -88 × (-1) = -8

Penjelasan:berapa = aberapa = bab = -8

Faktorisasi dr 82³ = 82²⁺¹ = 82² × 2 = 84 × 2 = 8Atau2³ = 82³ × 1 = 88 × 1 = 8

Maka-4 × 2 = -84 × (-2) = -8-8 × 1 = -88 × (-1) = -8

Jawab:

-2 x 4 = -8

-4 × 2 = -8

4 × (-2) = -8

-8 × 1 = -8

8 × (-1) = -8

Penyelesaian:

Sekarang, coba kamu perhatikan pola perkalian bilangan bulat berikut ini.

1. Bilangan positif x bilangan positif = bilangan positif

3 x 5 = 15

2 x 5 = 10

1 x 5 = 5

2. Bilangan negatif x bilangan positif = bilangan negatif

-1 x 5 = -5

-2 x 5 = -10

-3 x 5 = -15

3. Bilangan positif x bilangan negatif = bilangan negatif

3 x (-5) = -15

2 x (-5) = -10

1 x (-5) = -5

4. Bilangan negatif x bilangan negatif = bilangan positif

-1 x (-5) = 5

-2 x (-5) = 10

-3 x (-5) = 15

Dari pola tersebut dapat kita simpulkan:
