\(\frac{1995.1997-1}{1996.1995+1994}\)
\(=\frac{1995.1996+1995-1}{1996.1995+1994}\)
\(=\frac{1995.1996+1994}{1996.1995+1994}=1\)

-\(\frac{1995\cdot1997-1}{1995\cdot1996+1994}\)
=\(\frac{1995\cdot\left(1996+1\right)-1}{1995\cdot1996+1994}\)
=\(\frac{1995\cdot1996+1995\cdot1-1}{1995\cdot1996+1994}\)
=\(\frac{1995\cdot1996+1994}{1995\cdot1996+1994}\)
=1
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.
1995 x 1996 - 1997 / 1995 x 1994 +1993 = 3982017,001
(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.

1996 x 1995 - 996 - 1000 - 1996 x 1994
= 1996 x (1995 - 1994) - (996 + 1000)
= 1996 - 1996
= 0
\(\frac{1995\times1997-1}{1996\times1995+1994}\)
\(=\frac{1995\times\left(1996+1\right)-1}{1996\times1995+1994}\)
\(=\frac{1995\times1996+1995-1}{1996\times1995+1994}\)
\(=\frac{1995\times1996+1994}{1996\times1995+1994}\)
\(=1\)
