 Voi  gia tri nao cua x de K nguyen?

Answer 1

[Chu Công Đức]

Để K nguyên thì \(x+2003⋮x\)

mà \(x⋮x\)\(\Rightarrow\)Để \(x+2003⋮x\)thì \(2003⋮x\)

\(\Rightarrow x\in\left\{1;2003\right\}\)

Vậy \(x\in\left\{1;2003\right\}\)

Answer 2

\(x+2003:x\)

\(x:x=Đểx+2003:xthì2003:x\)

\(=>x\in\left\{\frac{1:2003}{1:2003}\right\}\)
