Question

2.) Verify the following:
(a) 18 x (7 + (-3)] = [18 x 7] + [18 × (-3)]​

Answer 1

Answer:

a 18 x [7 + –3] = [18 x 7] + [18 x –3] ⇒ 18 x 4 = 126 + –54 ⇒ 72 = 72 ⇒ L.H.S. = R.H.S. Hence verified.b–21 x [–4 + –6] = [–21 x –4] + [–21 x –6] ⇒ –21 x –10 = 84 + 126 ⇒ 210 = 210 ⇒ L.H.S. = R.H.S.

Step-by-step explanation:

Answer 2

18 x [7 +(-3)] = [18 x 7] +[18 x (-3)]

18× [7 - 3] = 126 + [-54]

18× 4 = 126 - 54

72 = 72

LHS = RHS
