1995*1997-1/1996*1995+1994

=1995*(1996+1)-1/1996*1995+1994

=1995*1996+1995-1/1996*1995+1994

=1995*1996+1994/1996*1995+1994

=1

ủng hộ mk nha!!

Bạn Nguyen Thi Nhung à! Câu trả lời của mình cũng giống như của bạn Hanyou Inu thôi.

\(\dfrac{1995x1997-1}{1996x1995+1994}=\dfrac{1995x\left(1996+1\right)-1}{1996x1995+1994}\)

\(=\dfrac{1995x1996+1995-1}{1996x1995+1994}=\dfrac{1995x1996+1994}{1996x1995+1994}=1\)

1

1995 x 1996 - 1997 / 1995 x 1994 +1993 = 3982017,001

3982017,001 nhé bạn >.<

\(\frac{1995\times1997-1}{1996\times1995+1994}\)

\(=\frac{1995\times\left(1996+1\right)-1}{1996\times1995+1994}\)

\(=\frac{1995\times1996+1995-1}{1996\times1995+1994}\)

\(=\frac{1995\times1996+1994}{1996\times1995+1994}\)

\(=1\)

=1997-1

phần

1996+1994

=1996/3990=998/1995

\(\frac{1995.1997-1}{1996.1995+1994}\)= \(\frac{1995.1997-1}{1996.1995+1995-1}\)= \(\frac{1995.1997-1}{1995.\left(1996+1\right)-1}\)= \(\frac{1995.1997-1}{1995.1997-1}\)= 1 

( vì tử số = mẫu số ) 

Tham khảo cách làm của mk nhé ! đúng 1000%

a)37/53x23/48x535353/373737x242424/232323

=37/53x23/48x53/37x24/23

=851/2544x1272/851

=1/2

1995.(1997-1996)

1995.(1994-1993)   = 1 nhé

(1995x1996-1997)/(1995x1994-1993)

=(1995x1996)/(1995x1994-1993+1997)

=(1995x1996)/(1995x1994+4)

=(1995x(1995+1)/(1995x1994+4)

=(1995x1995+1995)/(1995x1994+4)

=(1995x1995+1995-4)/(1995x1994)

=(1995x1995+1991)/(1995x1994)

=...Tự giải tiếp nhé, phần sau giải thích hơi dài.

K mình nhé, cảm ơn các bạn.
