Caranya tinggal isi saja hasil kalinya sesuai dgn angka di kolom a, b, dan c.

Saya coba bantu yang no. 1 dan 2 aja.

No. 3 dan 4 bisa coba sendiri.

1.

a = 1

b = 5

c = 4

a × b = 1 × 5 = 5

b × a = 5 × 1 = 5

(a × b) × c = 5 × 4 = 20

b × c = 5 × 4 = 20

a × (b × c) = 1 × 20 = 20

2.

a = -2

b = 6

c = -3

a × b = -2 × 6 = -12

b × a = 6 × (-2) = -12

(a × b) × c = -12 × (-3) = 36

b × c = 6 × (-3) = -18

a × (b × c) = -2 × (-18) = 36

Semoga membantu.

Note:

Untuk pengisian tabelnya, cukup isi hasil kalinya.
