(2004-2/2003)/1001怎样算
等式=(2003-1-2/2003)/1001
=(2003²-2003-2)/(1001X2003)
=(2003-2)(2003+1)/(1001X2003)
=2001X2004/(1001X2003)
=(2000+1)x2004/(1000x2003+1x2003)
=4010004/2005003
计算器呗
(2004-2/2003)/1001
=(2002+2-2/2003)/1001
=2+(4004/2003)/1001
=2又1001/2003
(2004-2/2003)1001
=(2002+2-2/2003)1001
=2002/1001+2/1001-2/(2003*1001)
=2+2/2001-(2/1001)*(1/2003)
=2+2/1001*(1-1/2003)
=2+(2/1001)*(2002/2003)
=2+4/2003
=4010/2003
