MN ơi giúp mình

Answer 1

  (-27).35-35.38+35.(-45)+35.10

=(-27).35+35.(-38)+35.(-45)+35.10

=35.[-27+(-38)+(-45)+10]

=35.(-100)

=-3500

Answer 2

( -27)  . 35 - 35 . 38 + 35. ( - 45 ) + 35 .10

= 35 . [ ( - 27 ) - 38 - 45 + 10 ]

= 35 . [ - 65 - 45 + 10 ]

= 35 . [ - 110 + 10 ]

= 35 . ( - 100)

= - 3500
