\(\frac{1995\times1994-1}{1993\times1995+1994}\)
\(=\frac{3978029}{3978029}\)
\(=3978029:3978029\)
\(=1\)
k mik nha bn
thank you very much
1995x1994-1/1993x1995+1994
=1995x[1993+1]-1/1993x1995+1994
=1995x1993+1995x1-1/1993x1995+1994
=1995x1993+1995-1/1993x1995+1994
=1995x1993+1994/1993x1995+1994
=1
