so sánh 2 số A và B nếu
\(A=-\frac{1}{2018}-\frac{3}{2017^2}-\frac{5}{2017^3}-\frac{7}{2017^4};B=\frac{-1}{2018}-\frac{7}{2017^2}-\frac{5}{2017^3}-\frac{3}{2017^4}\)
So sánh A và B nếu
\(A=\frac{-1}{2018}-\frac{3}{2017^2}-\frac{5}{2017^3}-\frac{7}{2017^4}\)
\(B=\frac{-1}{2018}-\frac{7}{2017^2}-\frac{5}{2017^3}-\frac{3}{2017^4}\)
So sánh
\(A=\frac{2018^n-2017^n}{2018^n+2017^n}\)+\(\frac{2017^n-2016^n}{2017^n+2016^n}\)
Cho tổng A=\(\frac{2018}{2017^2+1}+\frac{2018}{2017^2+2}+\frac{2018}{2017^2+3}+...+\frac{2018}{2017^2+n}+...+\frac{2018}{2017^2+2017}\)
(A có 2017 số hạng). Chứng tỏ A không là số nguyên
