Question

Verify the following:
(-21)×[(-6)+(-4)]=(-21)×(-6)+-2×(-4)

Answer 1

Answer:

To Verify the following

(−21)×[(−4)+(−6)]=[(−21)×(−4)]+[(−21)×(−6)]

Taking LHS we have

(−21)×[(−4)+(−6)]

=(−21)×[−4−6]

=(−21)×(−10)

=210

Now , Taking RHS we have

[(−21)×(−4)]+[(−21)×(−6)]

=84+126

=210

Answer 2

(-21) × [(-6)+(-4)] = [(-21) × (-6)]+[(-21)×(-4)]

= (-21) x [(-6) - 4] = (126) + (84)

= (-21) x (-10) = 210

= 210 = 210

Hence verified
