\(\frac{n^{2014}+n^{2013}+2}{n+1}\)=\(\frac{n\cdot n^{2013}+n^{2013}+2}{n+1}\)=\(\frac{n^{2013}\cdot\left(n+1\right)+2}{n+1}\)=\(\frac{n^{2013}\cdot\left(n+1\right)}{n+1}+\frac{2}{n+1}\)=\(n^{2013}+\frac{2}{n+1}\)
Để \(\frac{n^{2014}+n^{2013}+2}{^{n+1}}\)là số nguyên thì 2⁞n+1=>n+1 thuộc ước của 2
n+1 | 1 | -1 | 2 | -2 |
n | 0 | -2 | 1 | -3 |
