\(a.23.\left(75+25\right)+127.100\)
\(23.100+127.100\)
\(100.\left(127+23\right)\)
\(100.150\)
\(15000\)
\(b.\left(20+30\right)+\left(21+29\right)+22\)
\(50+50+22\)
\(100+22=122\)
\(23.75+25+23+127.100\)
\(=1725+25+23+12700\)
\(=1750+23+12700\)
\(=1773+12700\)

\(=50.2+22\)
\(=100+22\)
\(=122\)
thực hiện phép tính hợp lý
a) 23.75 + 25+23 + 127.100
b) 20+21 +22 +29+30
a.23.(75+25)+127.100
23.100+127.100
100.(127+23)
100.150
15000
b.(20+30)+(21+29)+22
50+50+22
100 + 22 = 122
=23.(75+25)+127.100
=23.100+127.100
=100.(23+127)
=100.150
=15000
15000 đó bạn hjhj
a,23.(75+250)+127.100
=23,100.100
=230000
b,20+30+(21+29)+22
=50+50+22
=100+22
=122
hihihi....
