Hôm nào tao phô cô giáo mày giám đăng bài lên đây à 

(48×0.75-240:10)-(16×0.5-16:4)

=(36-24)-(8-4)

=12-4

=8 

tk mk nhha bn

= 8 kick tui nha

=(36-24)-(8-4)

=12-4

=8

Vậy (48x0,75-240:10)-(16x0,5-16:4)=8

=(36-24)-(8-4)

=12-4

=8

Vậy (48x0,75-240:10)-(16x0,5-16:4)=8

=(36-24)-(8-4)

=12-4

=8

Vậy (48x0,75-240:10)-(16x0,5-16:4)=8

a) \(A=\left(48\cdot0,75-\frac{240}{10}\right)-\left(16\cdot0,5-\frac{16}{4}\right)\)

\(A=48\cdot0,75-24-16\cdot0,5-4\)

\(A=48\cdot0,5\cdot\frac{3}{2}-24-16\cdot0,5+4\)

\(A=72\cdot0,5-16\cdot0,5-24+4\)

\(A=0,5\left(72-16\right)-20\)

\(A=\frac{1}{2}\cdot56-20\)

\(A=28-20=8\)

b) \(B=937,246\cdot6,149+62,754\cdot6,149-6149\)

\(B=937,246\cdot6,149+62,754\cdot6,149-1000\cdot6,149\)

\(B=6,149\left(937,246+62,754-1000\right)\)

\(B=6,149\cdot0=0\)

=(2*24*0,75-24)-(4*4*0,5-4)=(1,5*24-24)-(2*4-4)=((1,5-1)*24)-((2-1)*4)=(0,5*24)-4=12-4=8
