Question

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

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

Hence , LHS = RHS
