Tolong dibantu ya plis di kumpulkan hari senin, kalau bisa sama caranya
Jawaban dan Penjelasan
Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.
1
a x b = 1 x 5 = 5
b x a = 5 x 1 = 5
(a x b) x c = 5 x 4 = 20
b x c = 5 x 4 = 20
a x (b x c) = 1 x 20 = 20
2
a x b = (-2) x 6 = -12
b x a = 6 x (-2) = -12
(a x b) x c = (-12) x (-3) = 36
b x c = 6 x (-3) = -18
a x (b x c) = (-2) x (-18) = 36
3
a x b = 3 x (-7) = -21
b x a = (-7) x 3 = -21
(a x b) x c = (-21) x 2 = -42
b x c = (-7) x 2 = -14
a x (b x c) = 3 x (-14) = -42
4
a x b = (-4) x (-8) = 32
b x a = (-8) x (-4) = 32
(a x b) x c = 32 x (-1) = -32
b x c = (-8) x (-1) = 8
a x (b x c) = (-4) x 8 = -32
a x b = 1 x 5 = 5
b x a = 5 x 1 = 5
(a x b) x c = 5 x 4 = 20
b x c = 5 x 4 = 20
a x (b x c) = 1 x 20 = 20
2
