TL:
2005 x 1999 -1000 x 2005 + 2005
=2005 x (1999 - 1000 + 1)
=2005 x 1000
=2005000
HT!~!
2005 nhân ( 1999 - 1000 ) = 1002995 đúng thì k sai thì xin lỗi
\(2005\times1999-1000\times2005+2005\)
\(=2005\times1999-1000\times2005+2005\times1\)
\(=2005\times\left(1999-1000+1\right)\)
\(=2005\times1000\)
\(=2005000\)
Trl :
2005 x 1999 - 1000 x 2005 + 2005
= ( 1999 - 1000 + 1 ) x 2005
= 1000 x 2005
= 2 005 000
