Question

29( 85 - 47 ) + 85( 47 - 29 )

Answer 1

29(85 - 47) + 85(47 - 29)

= 29.85 - 29.47 + 85.47 - 85.29

= (29.85 - 85.29) - (29 . 47 - 85.47)

= - 47.(29 - 85)

= -47.(-56 ) = 2632

Answer 2

29( 85 - 47 ) + 85( 47 - 29 )

= 29 . 85 - 29 . 47 + 85 . 47 - 85 .29

= -29 . 47 + 85 . 47

= 47(- 29 + 85 )

= 47 . 56 = 3136

Answer 3

\(29(85-47)+85(47-29)\)

\(=29\cdot85-29\cdot47+85\cdot47-85\cdot29\)

\(=(29\cdot85-85\cdot29)-(29\cdot47-85\cdot47)\)

\(=0-\left[29-85\right]\cdot47=0-(-2536)=2536\)

Answer 4

Sr nhầm kết quả đó là bằng 2632 nhé

Answer 5

29( 85 - 47 ) + 85( 47 - 29 )

= 29.38 + 85.18

= 1102 + 1530

=2632
