Hok tốt

\(12000-\left(1500.2+1800.3+1800.2:3\right)\)

đúng cho mình nha bạn

12000-(1500.2+1800.3+1800.2/3)

=12000-9600

=24000

chọn nha mình nha các bạn! ^^

12 000 - ( 1 500 . 2 + 1 800 . 3 + 1 800 . 2 : 3 )

= 12 000 - ( 3 000 + 5 400 + 1 200 )

= 12 000 - ( 8 400 + 1 200 )

= 12 000 - 9 600

= 2 400

1200-(1500x2+1800x3+1800x2:3)

=1200-(3000+5400+3600:3)

=1200-(3000+5400+1200)

=1200-(8400+1200)
