\(\left(2x-1\right)^{10}=\left(2x-1\right)^{11}\)
\(\Leftrightarrow\orbr{\begin{cases}2x-1=1\\2x-1=0\end{cases}}\)
\(\Leftrightarrow\orbr{\begin{cases}x=1\\x=\frac{1}{2}\end{cases}}\)
Vậy ...........
\(\Rightarrow\left(2x-1\right)^{11}-\left(2x-1\right)^{10}=0\)
\(\Rightarrow\left(2x-1\right)^{10}.\left[\left(2x-1\right)-1\right]=0\)
\(\Rightarrow\orbr{\begin{cases}\left(2x-1\right)^{10}=0\\\left(2x-1\right)-1=0\end{cases}\Rightarrow\orbr{\begin{cases}2x-1=0\\2x-1=1\end{cases}}}\)
\(\Rightarrow\orbr{\begin{cases}x=\frac{1}{2}\\x=1\end{cases}}\)
Vậy \(x\in\left\{\frac{1}{2};1\right\}\)
(2x-1)^10-(2x-1)^11=0
(2x-1)^10(1- 2x-1)=0
2x-1=0 hoặc 2x-1=1
x=1/2 hoặcx=1
Vậy...
