\[\sqrt{3x - 8} + \sqrt{1 - x}\]
\[\ \left\{ \begin{matrix} 3x - 8 \geq 0 \\ 1 - x \geq 0\ \ \ \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} 3x \geq 8 \\ x \leq 1\ \ \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} x \geq 2\frac{2}{3} \\ x \leq 1\ \ \ \\ \end{matrix} \right.\ \]
\[Ответ:нет\ таких\ значений.\]
