\[\log_{2}{(x - 2)} - 3 < 0\]
\[\left\{ \begin{matrix} \log_{2}(x - 2) - 3 < 0 \\ 3 - x \geq 0\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ \end{matrix} \right.\ \]
\[\left\{ \begin{matrix} \log_{2}(x - 2) < 3 \\ - x \geq - 3\ \ \ \ \ \ \ \ \ \ \ \ \ \\ \end{matrix} \right.\ \]
\[\left\{ \begin{matrix} \log_{2}(x - 2) < \log_{2}8 \\ x \leq 3\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ \end{matrix} \right.\ \]
\[0 < x - 2 < 8\]
\[2 < x < 10.\]
\[\left\{ \begin{matrix} x > 2\ \ \\ x < 10 \\ x \leq 3\ \ \\ \end{matrix} \right.\ \]
\[Ответ:2 < x \leq 3.\]
\[\sqrt{3 - x} - 2 < 0\]
