  1. ( 1 + 3 + 5 + ….. + 2005 ) . ( 125125 . 127 – 127127 . 125 )
    = ( 1 + 3 + 5 + ….. + 2005 ) . ( 125 . 1001 . 127 – 127127 . 125 )
    = ( 1 + 3 + 5 + ….. + 2005 ) . ( 125 . 127127 – 127127 . 125 )
    = ( 1 + 3 + 5 + ….. + 2005 ) . 0
    = 0

    ( 1+3+5+…+2005). (125125 . 127 – 127127 . 125)
    = ( 1+3+5+…+2005). (125125 . 127 – 127 . 1001 . 125)
    = (1+3+5+…+2005).(125125.127-127.125125)
    =(1+3+5+….+2005).0
    =0
    Vì tất cả mọi số nhân với 0 đều bằng 0
