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

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

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

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

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

= \(\frac{3990005}{3994}\)

thank you !! :))

1000 nha

cảm ơn bạn nha

( 1996 * 1997 + 1998 * 3 )  : ( 1997 * 1999 - 1997 * 1997 ) = 999,500751

đáp án: \(999.500751\)

tíc mình nha

999.500751

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

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

=(25+3*75-250):(1999*1998*1997*1996*1995*1994)

=(25+225-250):(1999*1998*1997*1996*1995*1994)

=(250-250):(1999*1998*1997*1996*1995*1994)

=0:(1999*1998*1997*1996*1995*1994)

=0                         

trả lời:

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

Bài làm:

\(\frac{1997.1996+1998.3+1944}{1994.1999-1997.1994}\)

\(=\frac{1997.1996+\left(1997+1\right).3+1994}{1994.\left(1999-1997\right)}\)

\(=\frac{1997.1996+1997.3+3+1994}{1994.2}\)

\(=\frac{1997.\left(1996+3\right)+1997}{1994.2}\)

\(=\frac{1997.\left(1999+1\right)}{1994.2}\)

\(=\frac{1997.2000}{1994.2}\)

\(=\frac{998500}{997}\)

Hc tốt!
