1996 x 1997 + 1998 x 3 + 1994 / 1997 x 1999 - 1997 x 1997

= 1996 x 1997 + ( 1997 + 1 x 3 ) + 1994 / 1997 x 1999 - 1997 x 1997

= 1996 x 1998 + 1 x 3 + 1994 / 1997 x 1999 - 1997 x 1997

= 3988008 + 3 + 1994 / 1997 x 1999 - 1997 x 1997

= 3990005 / 1997 x 1999 - 1997 x 1997

= 3990005 / ( 1999 - 1997 ) x 1997

= 3990005 / 3994

\(\frac{1996\times1997+1998\times3+1994}{1997\times1999-1997\times1997}\)

= \(\frac{1996\times1997+\left(1997+1\times3\right)+1994}{1997\times1999-1997\times1997}\)

= \(\frac{1996\times1998+1\times3+1994}{1997\times1999-1997\times1997}\)

= \(\frac{3990005}{1997\times1999-1997\times1997}\)

= \(\frac{3990005}{\left(1999-1997\right)\times1997}\)

= \(\frac{3990005}{3994}\)

\(\dfrac{1996\cdot1997+\left(1997+1\right)\cdot3+1994}{1997\cdot\left(1999-1997\right)}\) =  \(\dfrac{1996\cdot1997+3\cdot1997+1997}{1997\cdot2}\)

\(\dfrac{1997\cdot\left(1996+3+1\right)}{1997\cdot2}\)        =    \(\dfrac{2000}{2}\)=   \(1000\)

Ta có : ( 1998 * 1996 + 1997 * 11 + 1985 ) / ( 1997 * 1996 - 1995 * 1996 ) .

       = ( 1998 * 1997 - 1998 + 1997 * 11 + 1985 ) / 1996 * ( 1997 - 1995 ) .

       = [ 1997 * ( 1998 + 11 ) - 1998 + 1985 ] / 1996 * 2 .

       = [ 1997 * 2009 - 13 ] / 1996 * 2 .

       = [ 1996 * 2009 + 2009 - 13 ] / 1996 * 2 .

       = [ 1996 * 2009 + 1996 ] / 1996 * 2 .

       = [ 1996 * ( 2009 + 1 ) / 1996 * 2 .

       = 1996 * 2010 / 1996 * 2 .

       = 1005 .                                                                                                                                                                                  

bằng 1005 nha
