thanks b nha

Chữa lại mk làm sai ! =_="

12 . 35 + 35 . 182 - 35 . 94

= 35 . ( 12 + 182 - 94 ) 

= 35 . 100

= 3500

Ủng hộ tk Đúng nha ! 

=\(35\cdot\left(12+182-35\right)\)

\(=35\cdot165\)

\(=5775\)

12 x 35 + 35 x 182 - 35 x 94

= (12 + 182 - 94) x 35

= (200 - 94) x 35

= 106 x 35

= 3710

Học tốt!!!

12.35+35.182-35.94

k mik nhé 

hok tốt

35.(12+182-94)

= 35.100

thank you
