25.(75+49)-75.(25-49)
=25.124-75.(-24)
=3100-(-1800)
=3100+1800
=4900
HỌC TỐT !!!!
=25.75+25.49-75.25+75.49
=[(25.75)-(75.25)-(25.49)+(75.49)
=0-1225+3675
=2450
25(75+49)-75(25-49)
= 25.75+25.49-75.25-75.49
=(25.75-75.25)
xin lỗi mik chưa lm xong
\(25.\left(75+49\right)-75.\left(25-49\right)\)
\(=25.75+25.49-75.25+49.75\)
\(=75\left(25-25\right)+25.49+49.75\)
\(=75.0+25.49+49.3.25\)
\(=25.49+49.75\)
\(=49\left(25+75\right)=49.100=4900\)
25. (75 + 49) – 75. (25 – 49)
= 25.124-75.(-24)
=3100-(-1800)
=4900
