\(G=\dfrac{1^{2010}+2^{2010}+3^{2010}+...+10^{2010}}{2^{2010}+4^{2010}+....+20^{2010}}\\ =\dfrac{1^{2010}+2^{2010}+...+10^{2010}}{2^{2010}\left(1^{2010}+2^{2010}+...+10^{2010}\right)}\\ =\dfrac{1}{2^{2010}}\)

Theo bài ra, ta có:
\(G=\dfrac{1^{2010}+2^{2010}+3^{2010}+....+10^{2010}}{2^{2010}+4^{2010}+6^{2010}+....+20^{2010}}\)
\(\Rightarrow G=\dfrac{1^{2010}+2^{2010}+3^{2010}+....+10^{2010}}{2^{2010}\left(1^{1010}+2^{2010}+3^{2010}+....+10^{2010}\right)}\)
\(\Rightarrow G=\dfrac{1}{2^{2010}}\)
Vậy \(G=\dfrac{1}{2^{2010}}\)

Rút gọn :
Q = 12010 + 22010 + ....+ 102010 phần 22010 + 42010 + .....+ 202010
cho A: 1 + 2010 + 2010 mũ 2 + 2010 mũ 3 + 2010 mũ 4 + 2010 mũ 5 + 2010 mũ 6 + 2010 mũ 7
chứng minh A chia hết cho 2011
A=(1+2010)+2010 mũ 2+2010 mũ 3 +...+2010 mũ 6 + 2010 mũ 7
A=2011+2010 mũ 2(1+2010)+...+2010 mũ 6(1+2010)
A=2011+2010 mũ 2.2011+...2010 mũ 6.2011
