\(\left(2x-3\right)^4=\left(2x-3\right)^6\)
\(\Rightarrow\left(2x-3\right)\in\left\{1;-1;0\right\}\)

\(\left(2x-6\right)^5=\left(2x-6\right)^2\)
\(\Rightarrow\left(2x-6\right)^5-\left(2x-6\right)^2=0\)
\(\Rightarrow\left(2x-6\right)^2\left[\left(2x-6\right)^3-1\right]=0\)
\(\Rightarrow\orbr{\begin{cases}\left(2x-6\right)^2=0\\\left(2x-6\right)^3-1=0\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}2x-6=0\\\left(2x-6\right)^3=1\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}2x=6\\2x-6=1\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}x=3\\x=\frac{7}{2}\end{cases}}\)

(2x - 6)5 = (2x - 6)2
=> (2x - 6)5 - (2x - 6)2 = 0
=> (2x - 6)2.[(2x - 6)3 - 1] = 0
=> \(\orbr{\begin{cases}\left(2x-6\right)^2=0\\\left(2x-6\right)^3-1=0\end{cases}}\)
=> \(\orbr{\begin{cases}2x-6=0\\\left(2x-6\right)^3=1\end{cases}}\)
=> \(\orbr{\begin{cases}2x=6\\2x-6=1\end{cases}}\)
=> \(\orbr{\begin{cases}x=3\\2x=7\end{cases}}\)
=> \(\orbr{\begin{cases}x=3\\x=\frac{7}{2}\left(ktm\right)\end{cases}}\)
33x - 4 - x0 = 8
=> 33x - 4 - 1 = 8
=> 33x - 4 = 8 +1
=> 33x - 4 = 9
=> 33x - 4= 32
=> 3x - 4 = 2
=> 3x = 2 + 4
=> 3x = 6
=> x = 6 : 3 = 2

\(C=1+3+3^2+...+3^{2013}\)
\(\Rightarrow3C=3+3^2+3^3+...+3^{2014}\)
\(\Rightarrow3C-C=\left(3+3^2+3^3+...+3^{2014}\right)-\left(1+3+3^2+...+2^{2013}\right)\)
\(\Rightarrow2C=3^{2014}-1\)
Mà \(2C+1=3^{2x}\)
\(\Rightarrow3^{2014}-1+1=3^{2x}\)
\(\Rightarrow3^{2014}=3^{2x}\)
\(\Rightarrow2014=2x\)
\(\Rightarrow x=1012\)
Vậy x = 1012

a)vi (2x-6)^7=(2x-6)^5
=>2x-6=0 hoac 2x-6=1
=>x=3hoac x=7/2
b)(7-2x)^9=(7-2x)^3
=>7-2x=0 hoac 7-2x=1
=>x=7/2 hoac x=3
a) \(\left(2x-6\right)^7=\left(2x-6\right)^5\)
\(\Leftrightarrow\left[2\left(x-3\right)\right]^7=\left[2\left(x-3\right)\right]^5\)
\(\Leftrightarrow2^7\left(x-3\right)^7=2^5\left(x-3\right)^5\)
\(\Leftrightarrow128\left(x-3\right)^7=32\left(x-3\right)^5\)
\(\Leftrightarrow4\left(x-3\right)^7=\left(x-3\right)^5\)
\(\Leftrightarrow4\left(x-3\right)^7-\left(x-3\right)^5=0\)
\(\Leftrightarrow\left(x-3\right)^5\left[4\left(x-3\right)-1\right]=0\)
\(\Leftrightarrow\hept{\begin{cases}x-3=0\\4\left(x-3\right)-1=0\end{cases}}\Leftrightarrow\hept{\begin{cases}x=3\\x=\frac{7}{2}\\x=\frac{5}{2}\end{cases}}\)
\(\Rightarrow\hept{\begin{cases}x=3\\x=\frac{7}{2}\\x=\frac{5}{2}\end{cases}}\)

(-2x).(-2x)2.(-2x)3=k.x6
(-2x)6=k.x6
(-2)6.x6=k.x6
Vậy k=(-2)6=64

=> (2x - 6)2013 - (2x - 6)3 = 0
=> (2x - 6)3 [(2x - 6)2010 - 1 ] = 0
=> (2x - 6)3 = 0 => 2x - 6 = 0 => 2x = 6 => x = 3
hoặc (2x - 6)2010 - 1 = 0 => (2x - 6)2010 = 1 => 2x - 6 = 1 =>2x = 7 =>x = 7/2
Vậy x = 3 ; x = 7/2
