Question

\(\dfrac{1996x1995x996}{1000+1996x1994}\)

Answer 1

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

Ta có: \(\frac{1996\cdot1995-996}{1000+1996\cdot1994}\)

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

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

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