2x+1.22009=22010
2x+1=22010:22009
2x+1=21
=>x+1=1
x=1-1
x=0
vậy x = 0
![](https://rs.olm.vn/images/avt/0.png?1311)
2x + 1 . 22009 = 22010
2x + 1 = 22010 : 22009
2x + 1 = 21
=> x + 1 = 1
=> x = 1 - 1
=> x = 0

\(2^{x+1}.2^{2009}=2^{2010}\)
=> \(2^{x+1}=2^{2010}:2^{2009}=2^1\)
=> x+1=1
=> x=0
2x+1.22009=22010
2x.2 =22010:22009
2x =2:2
2x =1
2x =20
=> x=0.

2^x=2^2010−2^2009
2^x=2^2009(2−1)2^x=2^2009
⇒x=2009

\(2^{x+1}\cdot2^{2009}=2^{2010}\)
\(2^{x+1}=2^{2010}:2^{2009}\)
\(2^{x+1}=2\)
\(x+1=1\)
\(x=0\)
\(2^{x+1}.2^{2009}=2^{2010}\)
\(2^{x+2010}=2^{2010}\)
\(2^x=1\)
\(\Rightarrow x=0\)

2x+1 . 22009 = 22010
=> 2x+1 = 22010 : 22009
=> 2x+1 = 21 => x + 1 = 1 => x = 0
Vậy x = 0
