Xin mọi người đừng k sai mình nhé !

    -75.(18-65)-65.(75-18) 

= −75.18 + 75.65 − 65.75 + 65.18 

= −75 + 65 .18 + 75. 65 − 65 

= −10.18 + 75.0 

= −180

\(65\left(75+189\right)-75\left(65+189\right)\)

\(=65.75+65.189-75.65-75.189\)

\(=\left(65.75-75.65\right)+\left(65.189-75.189\right)\)

\(=0+\left(65-75\right).189\)

\(=0+\left(-10\right).189\)

\(=-10.189\)

\(=-1890\)

\(\left(-75\right)\left(18-65\right)-65\left(75-18\right)\)

\(=\left(-75\right).18-\left(-75\right).65-65.75+65.18\)

\(=\left(-75\right).18+75.65-65.75+65.18\)

\(=18.\left[\left(-75\right)+65\right]+\left(75.65-65.75\right)\)

-75x(18-65)-65x(75-18) = -75x(-47) - 65x57

=3525-3705=-180. 

k nha. thnk 

= (-75) x 18 - (-75) x 65  - 65 x 75 - 65 x 18

= (-75) x 18 - 65 x 18 - (-75) x 65 - 65 x 75

= (-75 - 65) x 18 - 65 x (-75 - 75)

= -140 x 18 - 65 x (-150)

= 7230

a.={75+(-75)}+{15+(-32)}+-55

=0+-17+-55

=0+{(-17)+(-55)

=0+-75

=-75

b. =(35+35)+(65-65)+(24-24)

=70+0+0

=70

không biết đúng hay sai mong mấy bạn thông cảm vì mình cũng không chắc chắn !

35.(34+38)+65.(75+45)

35.72 + 65.120

35 * 34 + 35 * 34 + 65 * 75 + 65 * 45

= 34* ( 35+35) + 65* ( 75 + 45)

= 34 * 70 + 65* 120

= 2380 + 7800

= 10180

\(=35.\left(34+34\right)+65.\left(75+45\right)\)

\(=35.68+65.120=2380+7800=10180\)

35 . 34 + 35+38 +65 +75 +65 . 45 

= 35 .( 34 + 1 ) + 38 + 65 ( 75 + 45 )

Chúc bạn học tốt 

35 x 34 + 35 x 65 + 65 x 75 + 65 x 45

= ( 35 x 34 + 35 x 65 ) + ( 65 x 75 + 65 x 45 )

= 35 x ( 34 + 65 ) + 65 x ( 75 + 45 )

= 35 x 99 + 65 x 120

= 3465 + 7800

= 11265

\(35.34+35.65+65.75+65.45\)

=\(35.\left(34+65\right)+65.\left(75+45\right)\)

= 35. 99 +65.120
