Answer:
2.(a) 18 x (7 + (-3)) = (18 x 7) + (18 x (-3))
= 18 x ( 7 - 3) = 126 + (18 x - 3)
= 18 x 4 = 126 + (-54)
= 72 = 126 - 54
= 72 = 72(ANS)
THEREFORE, HENCE verified
- 2.(b) (-21) x ((-4) + (-6)) = ((-21) x (-4)) + ((-21) x (-6))= (-21) x (-4 - 6) = (-21 x -4) + (-21 x -6) = (-21) x (-10)= 84 + 126 = 210 = 210 (ANS) THEREFORE, HENCE verified.
