\[\sqrt{2x - 5} + \sqrt{2 - x}\]
\[\left\{ \begin{matrix} 2x - 5 \geq 0 \\ 2 - x \geq 0\ \ \\ \end{matrix}\text{\ \ } \right.\ \text{\ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} 2x \geq 5 \\ x \leq 2\ \ \\ \end{matrix}\text{\ \ } \right.\ \text{\ \ \ \ \ }\]
\[\left\{ \begin{matrix} x \geq 2,5 \\ x \leq 2\ \ \ \\ \end{matrix} \right.\ \]
\[Ответ:нет\ таких\ значений.\]
