Answer 2

$\huge\mathbb\pink{Answer⬇⬇}$

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 ) × [ ( -4 ) + ( - 6 ) ]= ( - 21 ) × ( - 10 )

= ( -21 ) × [ ( -4 ) + ( - 6 ) ]= ( - 21 ) × ( - 10 )= 210

RHS

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

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

=210

= 210=210

∴ LHS = RHS

Hence verified
