\(\left(a\right)314+345\cdot10\div2=314+345\cdot5=314+1725=2039\)
\(\left(b\right)467-421\cdot100\div5=467-421\cdot20=467-8420=-7953\)
Trả lời:
a,\(314+345\times10\div2\)
\(=314+345\times5\)
\(=314+1725\)
\(=2039\)
b, \(467-421\times100\div5\)
\(=467-421\times20\)
\(=467-8420\)
\(=-7953\)
Chúc bạn học tốt
a,\(314+345\times10:2\)
\(=314+345\times5\)
\(=314+1725\)
\(=2039\)
b,\(467-421\times100:5\)
\(=467-421\times20\)
\(=467-8420\)
\(=-7953\)
Hok tốt!!!
