Trả lời :

\(-3752\) \(-\) \(\left(29-3632\right)\) \(-\) \(51\)

= - 3752 - 29  + 3631 - 51

= - ( 3752 - 3632 ) - ( 29 + 51 )

= - 129 - 80

= - 200

Học tốt

TL :

\(-3752\left(29-2632\right)-51=3752-\left(-3603\right)-51\)

\(-3756+3603-51=-149-51=-200\)

Vậy kết quả = \(-200\)

Hok tốt

\(-3752-\left(29-3632\right)-51\)

\(=-3752-29+3631-51\)

\(=-\left(3752-3632\right)-\left(29+51\right)\)

\(=-129-80\)

\(=-200\)

_Trl :

- 3752 - ( 29 - 3632 ) - 51

= - 3752 - 29 + 3632 - 51

 = - ( 3752 - 3632 ) - ( 29 + 51 )

= - 120 - 50

= - 200

s lại = -200

- 3752 - ( 29 - 3632 ) - 51

= (-3752) + 3603 - 51 

= (-149) - 51

= -(149 + 51)

= (-200)

\(-3752-\left(29-3632\right)-51=-3752-\left(-3603\right)-51\)

-200 nha bạn

b. 4524-(864-999)-(36+3999)

  = 4524-864+999-36-3999

  =  3660+999-36-3999

  = 3660 +339+660-36-3999

  =3999+660-36-3999

  = (3999-3999)+(660-36)

Bài 1:

Bài 2:

b: \(=-25\cdot47+25\cdot32-25\cdot32+32\cdot47=47\cdot7=329\)

-3752 - ( 29 - 3632 - 51 ) 

= -3752 - 29 + 3632 + 51

= ( -3752 + 3632 ) - 29 + 51

= -120 - 29 + 51

= -98

Ko biết đúng hay ko nữa 

=  -98 nha bn

chucas bn hok tốt
