Ta có : \(\left(x-7\right)^{x+1}-\left(x-7\right)^{x+11}=0\)

\(\left(x-7\right)^{x+1}\cdot\left[1-\left(x-7\right)^{x+10}\right]=0\)

\(\Leftrightarrow\left[{}\begin{matrix}\left(x-7\right)^{x+1}=0\\1-\left(x-7\right)^{x+10}=0\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}x-7=0\\x-7=1\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}x=7\\x=8\end{matrix}\right.\)

Vậy \(x\in\left\{7;8\right\}\)
