Answer 2

cậu cho sai đề bài

Answer 3

Sửa đề : \(\frac{1996\cdot1995-996}{1996\cdot1994+1000}\)

\(=\frac{1996+\left(1994+1\right)-996}{1996\cdot1994+1000}\)

\(=\frac{1996\cdot1994+\left(1996-996\right)}{1996\cdot1994+1000}\)

\(=\frac{1996\cdot1994+1000}{1996\cdot1994+1000}=1\)

Answer 4

\(\frac{1996\cdot995-996}{1996\cdot1994+1000}\)

\(=\frac{1996+\left(1994+1\right)-996}{1996\cdot1994+1000}\)

\(=\frac{1996\cdot1994+\left(1996-996\right)}{1996\cdot1994+1000}\)

\(=\frac{1996\cdot1994+1000}{1996\cdot1994+1000}\)

\(=1\)
