\(M=2^{2010}-\left(2^{2009}+2^{2008}+...+2^1+2^0\right)\)
\(2^{2010}-M=2^0+2^1+...+2^{2008}+2^{2009}\)
\(2\left(2^{2010}-M\right)=2+2^2+...+2^{2009}+2^{2010}\)
\(2\left(2^{2010}-M\right)-\left(2^{2010}-M\right)=\left(2+2^2+...+2^{2009}+2^{2010}\right)-\left(2^0+2^1+...+2^{2008}+2^{2009}\right)\)
\(2^{2010}-M=2^{2010}-1\)
\(M=2^{2010}-2^{2010}+1\)
\(M=1\)
\(R=2^{2010}-\left[2^{2009}+2^{2008}+...+2^1+2^0\right]\)
\(2^{2010}-R=2^0+2^1+...+2^{2008}+2^{2009}\)
\(2^{2011}-2R=2^1+2^2+...+2^{2009}+2^{2010}\)
\(\left(2^{2011}-2R\right)-\left(2^{2010}-R\right)=2^{2010}-1\)
\(2^{2010}-R=2^{2010}-1\)
\(R=2^{2010}-2^{2010}+1=0+1=1\)
\(N=2^{2009}+2^{2008}+...+2+1\)
\(\Leftrightarrow2N=2^{2010}+2^{2009}+...+2^2+2\)
=>\(N=2^{2010}-1\)
\(M=2^{2010}-2^{2010}+1=1\)
M=2^2010-(2^2009+2^2008+2^2007+...+2^1+2^0)
M=22010-22009-22008-22007-...-21-20
=>2M=22011-22010-22009-22008-...-22-21
=>2M-M=22011-22010-22009-22008-...-22-21-(22010-22009-22008-22007-...-21-20)
=>M=22011-22010-22009-22008-...-22-21-22010+22009+22008+22007+...+21+20
=22011-22010-22010+20
=22011-2.22010+1
=22011-22011+1
=1
vậy M=1
đúng mjk với nha
ĐẶt A = 2^0 + 2^1 +.. + 2^2009
2A = 2^ 1 + 2^2 +.... + 2^2009 +2 ^2010
2A - A = 2^1 + 2^2 + . ... + 2^2009 +2^2010 - 2 ^0 - 2^1 - 2^2 -..-2^3009
A = 2^2010 - 2^0 = 2^2010 - 1
M = 2^2010 - A = 2^2010 - (2^2010 - 1) = 2^2010 - 2^2010 +1 = 1
32010- ( 32009 + 32008 + ... + 3 + 1 )
Đặt A = 1 + 3 + ... + 32009
=> 3A = 3 + 32 + ... + 32010
=> 3A - A = 32010 - 1
Nên 32010 - ( 32010 - 1 ) = 1
\(M=2^{2010}-\left(2^{2009}+2^{2008}+...+2^1+2^0\right)\)
\(2^{2010}-M=2^{2009}+2^{2008}+...+2^1+2^0\)
\(2\left(2^{2010}-M\right)=2^1+2^2+....+2^{2009}+2^{2010}\)
\(2\left(2^{2010}-M\right)-\left(2^{2010}-M\right)=\left(2^1+2^2+....+2^{2009}+2^{2010}\right)-\left(2^0+2^1+...+2^{2008}+2^{2009}\right)\)
\(2^{2010}-M=2^{2010}-1\)
\(M=2^{2010}-2^{2010}+1\)
\(M=1\)
M=22010-(22009+22008+22007+...+21+20)
M=22010-22009-22008-22007-...-21-20
=>2M=22011-22010-22009-22008-...-22-21
=>2M-M=22011-22010-22009-22008-...-22-21-(22010-22009-22008-22007-...-21-20)
=>M=22011-22010-22009-22008-...-22-21-22010+22009+22008+22007+...+21+20
=22011-22010-22010+20
=22011-2.22010+1
=22011-22011+1
=1
Vậy M=1
Đặt M = 2^2010 - A
\(2A=2+2^2+...+2^{2010}\)
\(2A-A=\left(2+2^2+...+2^{2010}\right)-\left(1+2+...+2^{2009}\right)\)
\(A=2^{2010}-1\)
\(\Rightarrow M=2^{2010}-2^{2010}+1\)
\(\Rightarrow M=1\)
Vậy,.............
\(M=2^{2010}-2^{2009}-2^{2008}-...-2-1\)
\(\Rightarrow2M=2^{2011}-2^{2010}-2^{2009}-...-2^2-2\)
\(\Rightarrow2M-M=2^{2011}-2^{2010}-1=2^{2010-1}\)
C = 22010 - ( 22009 + 22008+ ...+ 21 + 20 )
\(C=2^{2010}-2^{2009}-2^{2008}-...-2^0\)
\(2C=2^{2011}-2^{2010}-2^{2009}-...-2^1\)
\(2C-C=C=2^{2011}-1\)
\(C=2^{2010}-\left(2^{2009}+2^{2008}+....+2^1+2^0\right)\)
\(C=2^{2010}-2^{2009}-2^{2008}-.....-2^0\)
\(2C=2\left(2^{2010}-2^{2009}-...-2^0\right)\)
\(=>C=2C-C=2^{2011}-1\)
