Verify the following(i) 18 x 7 + (-3) = [18 x 7] + [18 x (-3)](ii) (-21) x [(-4) + (-6)] = [(-21) x (4)] + [(-21) x (-6)] |
Answer» (i) 18 x [7 + (-3)] = 18 x 4 = 72 and [18 x 7] + [18 x (-3)] = 126 – 54 = 72 so 18 x [7 + (-3)] = [18 x 7] + [18 x (-3)] (ii) (-21) x [(- 4) +(6)] = (-21) x (- 4 – 6) | = (-21) x (-10) = 210 and [(21) x(-4)] + [(-21) x (-6)] = 84 + 126 = 210 so (-21) x [(- 4) + (-6)] = [(-21) x (- 4)] + [(-21) x (-6)] |
