12000 – (1500.2 + 1800.3 + 1800.2:3)
= 12 000 – (3000 + 5400 + 3600 : 3)
= 12000 – (3000 + 5400 + 1200)
= 12000 – 9600
= 2400

Trả lời :
= 12000 - ( 3000 + 5400 + 1200 )
= 12000 - 9600
= 24000
~ Chúc hok tốt nha ~
12000-(1500.2 + 1800.3 +1800.2/3)
=12000-(3000+5400+1200)
=12000-8600
=3400

ko biết có đúng ko!^^
1200-(1500.2+1800.3+1800.2:3)
=1200-[3000 + 1800.(3+2):3]
= 1200-(3000+1800.5:3)
=1200-(3000+9000:3)
=1200-(3000+3000)
=1200 - 6000
= -4800

12000-(1500.2+1800.3+1800.2:3)
= 12000-( 4500.2:3+6900.2:3+1800.2:3)
= 12000-( 4500+6900+1800) .2:3
= 12000- 12600.2:3
= 12000-4200
= 7800
\(12000-\left[1500.2+1800.3+\left(1800.2\right):3\right]\)
\(=12000-\left[3000+5400+3600:3\right]\)
\(=12000-\left[3000+5400+1200\right]\)
\(=12000-9600\)
\(=2400\)
