Question

Tính giá trị biểu thức :

\(12000-\left(1500\cdot2+1800\cdot3+1800\cdot2:3\right)\)

Answer 1

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

= \(12000-\left(3000+5400+1200\right)\)

\(=12000-9600\)

\(=2400\)

Answer 2

\(\text{12000-(1500.2+1800.3+1800.2:3)}\)

\(\text{=12000-(3000+540+1200)}\)

\(\text{=12000-96000}\)

\(\text{=2400}\)

Answer 3

12000 - (1500 : 2 + 1800 : 3 + 1800 : 2 : 3)

=12000 - (750 + 600 + 300)

=12000 - 1650

=10350

Answer 4

12000−(1500.2+1800.3+1800.2:3)

= 12000−(3000+5400+1200)

=12000−9600

=2400

Answer 5

12000-(1500.2+1800.3+1800.2:3)

=1200-(3000+5400+1200)

=12000-9600

=2400
