24.(56-45)+56.(-24-45)

= 24.56-24.45-56.24-56.45

= (24.56-56.24)-(24.45+56.45)

 24 . (56 - 45) + 56(-24 - 45)

= 24 . 56 - 24 . 45 + 56 . (-24) - 56 . 45

= [24 . 56 + 56 . (-24)] - (24 . 45 + 56 . 45)

24(16 - 5) - 16(24 - 5)

\(24\left(16-5\right)-16\left(24-5\right)\)

\(=24.16-24.5-16.24+16.5\)

\(=\left(24.16-24.16\right)+\left(16.5-24.5\right)\)

\(=0+5.\left(-8\right)\)

\(=-40\)

24.(16-5)-16.(24-5)

= 24.16 - 24.5 - 16.24 + 16.5

= 24.( 16 - 16 ) + 5 . ( -24 +16 )

= 24.0 + 5 .( -8 )

= -40

học tốt

Trả lời :

-40

Hok tốt nhé bạn ((:

24.(16-5)-16.(24-5)

=24.16-5-16.24-5

=(24-24).(16-16).(5-5)

=0.0.0

=0

k cho mình nha

24 x (16 - 5) - 16 x (24 - 5)

= 24 x 11 - 16 x 19

= 264 - 304

= -40

Học tốt!!!

Hình như sai đề

mình ko phải lớp 6

24.(16-5)-16.(24-5)

= 24 . 16 - 24 . 5 - 16 . 24 + 5. 16

= 5 . 16 - 24 . 5

= 5. ( 16 - 24 )

= 5 . ( - 8)

= - 40

Lê Thị Thanh Xuân k giups đc thì đừng lm v nhé

24 . ( 16 - 5 ) - 16 . ( 24 - 5 ) 

=24.16-24.5-16.24+16.5

=-24.5+16.5

=5(-24+16)

=5.(-8)

=-40

Chúc bạn học tốt !
