\(=2090.2+2010.2\)
\(=2.\left(2090+2010\right)\)
\(=2.4100=8200\)
Hok tốt nhé
2010 + 2090 + 2090 + 2010=8200
k to voi cac ban!
bang 8200 đúng không ta
nếu đúng thì k cho mình nha
2010 + 2090 + 2090 + 2010
= ( 2010 + 2090 ) + ( 2010 + 2090 )
= 4100 + 4100
= 8200
2010+2090+2090+2010
=2010.2+2090.2
=4020+4180
2010 + 2090 +2090 +2010
= (2010+2010) + (2090 +2090)
= 4020 + 4180
=8200
tk nhé
2010+2090+2090+2010
=2010.2+2090.2
=4020+4180
=8200
