Question

18×[7 + (–3)]=[18 × 7]+[18 × (–3)] Verify it.

Answer 1

Heya !!



18 × { 7 + (-3) } = ( 18 × 7 ) + { 18 × (-3) }





=> 18 × ( 7 - 3 ) = ( 18 × 7 ) + ( 18 × - 3 )





=> 18 × 4 = 126 + ( -54 )





=> 18 × 4 = 126 - 54



=> 72 = 72.




LHS = RHS.





Hence,




18 × { 7 + (-3) } = ( 18 × 7 ) + { 18 × (-3 ) }.

Answer 2

$\bf\sf{Solution:}$

18 × [ 7 + (–3) ] = [18 × 7 ] + [18 × (–3) ]

=> 18 × ( 7 - 3 ) = ( 18 × 7 ) + ( 18 - 3 )

=> 18 × 4 = 126 - 54

=> 72 = 72

$\huge\boxed{LHS = RHS}$

$\textbf{Hope it helps}$
