Question

verify the following (-21)×[(-4)+(-6)]=[(-21)×(-4)]+[(-2)×(-6)]​

Answer 1

$\huge \color{red} \boxed{ \colorbox{pink}{AnsWer}}$

( -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

Answer 2

Answer:

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

(-21)×[-4-6] = 84 + 126

(-21)×(-10) = 210

210 = 210
