muốn giải nhanh thì bấm máy tính đi
Thực hiện phép tính B=1434:{[(216+184:8).3]}
Tính theo cách hợp lí :
400 - ( ( ( 184 + 216 ) : 8 ) . 6 )
A =4*5^2-2^8:2^6
B =1449-{[(216+184):8]*9}

347.22-22(216+184):8
\(\dfrac{7256\cdot4375-725}{3650+4375\cdot7255}\)
a) Ta có: \(347\cdot2^2-2^2\left(216+184\right):8\)
\(=347\cdot4-4\cdot400:8\)
\(=1388-200=1188\)
