Ta có: \(H=2^{2010}-2^{2009}-2^{2008}-...-2-1\)
\(=2^{2010}-\left(2^{2009}+2^{2008}+...+2+1\right)\)
Đặt \(A=2^{2009}+2^{2008}+...+2+1\)
\(\Rightarrow2A=2^{20010}+2^{2009}+...+2^2+2\)
\(\Rightarrow2A-A=\left(2^{20010}+2^{2009}+...+2^2+2\right)-\left(2^{2009}+2^{2008}+...+2+1\right)\)\(\Rightarrow A=\left(2^{2010}-1\right)+\left(2^{2009}-2^{2009}\right)+\left(2^{2008}-2^{2008}\right)+...+\left(2-2\right)\)\(\Rightarrow A=2001-1\)
\(\Rightarrow H=2^{2010}-\left(2^{2010}-1\right)\)
\(\Rightarrow H=2^{2010}-2^{2010}+1=1\)
Thay \(H=1\) vào biểu thức \(2010^H\)
\(\Rightarrow2010^H=2010^1=1\)
Vậy \(2010^H=1\)
Ta có: \(H=2^{2010}-2^{2009}-2^{2008}-...-2-1\)
\(=2^{2010}-\left(2^{2009}+2^{2008}+...+2+1\right)\)
Đặt \(A=2^{2009}+2^{2008}+...+2+1\)
\(\Rightarrow2A=2^{20010}+2^{2009}+...+2^2+2\)
\(\Rightarrow2A-A=\left(2^{20010}+2^{2009}+...+2^2+2\right)-\left(2^{2009}+2^{2008}+...+2+1\right)\)\(\Rightarrow A=\left(2^{2010}-1\right)+\left(2^{2009}-2^{2009}\right)+\left(2^{2008}-2^{2008}\right)+...+\left(2-2\right)\)\(\Rightarrow A=2001-1\)
\(\Rightarrow H=2^{2010}-\left(2^{2010}-1\right)\)
\(\Rightarrow H=2^{2010}-2^{2010}+1=1\)
Thay \(H=1\) vào biểu thức \(2010^H\)
\(\Rightarrow2010^H=2010^1=1\)
Vậy \(2010^H=1\)
\(H=2^{2010}-2^{2009}-...-2^2-2-1\)
\(2H=2^{2011}-2^{2010}-...-2^3-2^2-2\)
\(2H-H=\left(2^{2011}-2^{2010}-...-2^3-2^2-2\right)-\left(2^{2010}-2^{2009}-...-2^2-2-1\right)\)
\(H=2^{2011}-2^{2010}-2^{2010}-1\)
\(H=2^{2011}-\left(2^{2010}+2^{2010}\right)-1\)
\(H=2^{2011}-2.2^{2010}-1\)
\(H=2^{2011}-2^{2011}-1\)
\(H=-1\)
Suy ra \(2017^H=2017^{-1}=\frac{1}{2017}\)
Vậy \(2017^H=\frac{1}{2017}\)
Chúc bạn học tốt
\(C=\frac{\frac{1}{2008}-\frac{1}{2009}-\frac{1}{2010}}{\frac{5}{2008}-\frac{5}{2009}-\frac{5}{2010}}+\frac{\frac{2}{2007}-\frac{2}{2008}-\frac{2}{2009}}{\frac{3}{2007}-\frac{3}{2008}-\frac{3}{2009}}\)
\(=\frac{\frac{1}{2008}-\frac{1}{2009}-\frac{1}{2010}}{5.\left(\frac{1}{2008}-\frac{1}{2009}-\frac{1}{2010}\right)}+\frac{2.\left(\frac{1}{2007}-\frac{1}{2008}-\frac{1}{2009}\right)}{3.\left(\frac{1}{2007}-\frac{1}{2008}-\frac{1}{2009}\right)}\)
\(=\frac{1}{5}+\frac{2}{3}\)
\(=\frac{13}{15}\)
\(2^{225}=\left(2^3\right)^{75}=8^{75}< 9^{75}=\left(3^2\right)^{75}=3^{150}\)
\(2^{2009}+2^{2008}+.......+2+1=b\)
\(\Rightarrow2b=2^{2010}+2^{2009}+.........+2^2+2\)
\(\Rightarrow2b-b=2^{2010}-1\Rightarrow b=2^{2010}-1\)
\(\Rightarrow A=2^{2010}-b=2^{2010}-\left(2^{2010}-1\right)=1\)
Theo qui luật; H = 1.
=> 2010H = 20101 = 2010.
bang 2010^1=2010
