Question

(-105) . 19 + (-76) .105 - 5 . 105

Answer 1

(-105) . 19 + (-76) . 105 - 5 . 105

= 105 . (-19) + (-76) . 105 - 5 . 105

= 105 . [(-19) + (-76) - 5]

= 105 . (-100)

= -10500

Answer 2

= ( - 105 )( 19 - 76 - 5 )

= ( - 105 )( - 62 )

= 6510

Answer 3

= ( 105 )( - 19 - 76 - 5 )

= ( 105 )(  -100 )

= -10500

Answer 4

= ( -105 )( 19 + 76 + 5 )

= ( -105 )( 100 )

= - 10500

Answer 5

   (-105).19 + (-76).105 - 5.(105)

= (-105). 19 + 76.(-105) + 5.(-105)

= (-105). (19 + 76 + 5)

= -105. 100

= -10500
