Question

a.) (-21) ×[(-4)+(-6)] [(21) x(4)]+[(21)×(-6)​

Answer 1

Step-by-step explanation:

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

∴ LHS = RHS

Hence verified
