Jawablah pertanyaan berikut

Jawaban:

a = (-3)

b = (-5)

c = 2

$frac{21 times 3b}{c} \ = frac{21 times 3.( - 5)}{2} \ = frac{21 times ( - 15)}{2} \ = frac{ - 315}{2} \ = - 157.5$

$(a times b) times 3c \ = (( - 3) times ( - 5)) times 3.(2) \ = (15) times (6) \ = 90$

Semoga membantu.

Mohon di cek kembali.
