Question

2. Verify the following
a) 27 x [6+(4)] = 127 x 6] + [27(-4)
b) (-32)*((-3) +(-7)]
= [(-32) (-3)] + [(-32)*(-7)]​

Answer 1

Answers:

(a) 27 × [6+(-4)] = [27 × 6] + [27 × (-4)]

27 × [6 - 4]= 162 + [-108]

27 × 2 = 162 - 108

54 = 54

L.H.S = R.H.S

(b) (-32)×[(-3)+(-7)]=[(-32)×(-3)]+[(-32)×(-7)]

(-32) × [-10] = [96] + [224]

320 = 320

L.H.S = R.H.S
