Question

A=2006-2005-1/2004*2006+2006

Giải ra nha

Answer 1

\(1-\left(\frac{1}{2004}.2006\right)+2006\)

\(1-\frac{1003}{1002}+2006\)

\(-\frac{1}{1002}+2006=2005,999002\)

Answer 2

Đề bài theo mình là \(A=\frac{2006.2005-1}{2004.2006+2006}\)

\(=\frac{2006.2004+2006-1}{2004.2006+2006}\)

\(=\frac{2006.2004+2005}{2004.2006+2006}\)

\(=\frac{2006.2004+2006}{2004.2005+2006}-\frac{1}{2004.2006+2006}\)

\(=1-\frac{1}{2005.2006}\)
