\(\frac{1996\times1995-996}{1000+1996\times1994}=\frac{1996\times1994+1996-996}{1996\times1994+1000}=\frac{1996\times1994+1000}{1996\times1994+1000}=1\)
1996 x 1995 - 996 1000 + 1996 x 1994
= 3982020 - 996 = 1000 + 3980024
= 3981024 = 3981024
2 kết quả bằng nhau!!!!!!

1996 * 1995 - 996 / 1996 * 1994 + 1000
= 1996 * 1994 + ( 1996 - 996 ) / 1996 * 1994 + 1000
= 1996 * 1994 + 1000 / 1996 * 1994 + 1000

**** cho mink nha !
K qua la bang 1 nha bn !
1996 x 1995 - 996 / 1000 + 1996 x 1994 = 1

k cho mk nha!!

1996 x 1995 - 996 - 1000 - 1996 x 1994
= 1996 x 1995 - (996 - 1000) - 1996 x 1994
= 1996 (1995 -1 - 1994)
= 0
Mk không biết gõ dấu phân số để ngăn cách
Ok xin lỗi nhak babe
1996 * 1995 - (996 + 1000 + 1996*1996)
= 1996*1995 - (1996 x (1 + 1996))
= 1996*(1995 - 1996 - 1)
= 1996* -2
=-3992
1996 * 1995 - (996 + 1000 + 1996*1996)
= 1996*1995 - (1996 x (1 + 1996))
= 1996*(1995 - 1996 - 1)
= 1996* -2
=-3992
