Answer:
SOLUTION
TO VERIFY
(-21)×[(-4)+(-6)]=[(-21)×(-4)]+[(-21)×(-6)]
EVALUATION
We have to verify
( -21 ) × [ ( -4 ) + ( - 6 ) ]
= [ ( -21 ) × ( -4 ) ] + [ ( -21 ) × ( - 6 ) ]
LHS
= ( -21 ) × [ ( -4 ) + ( - 6 ) ]
= ( - 21 ) × ( - 10 )
= 210
RHS
[ ( -21 ) × ( -4 ) ] + [ ( -21 ) × ( - 6 ) ]
= 84 + 126
= 210=210
∴ LHS = RHS
Hence verified
