Решение:
Знаменатель: \(1-\sqrt{2}\). Сопряженное выражение: \(1+\sqrt{2}\).
\[ \frac{23-24\sqrt{2}}{1-\sqrt{2}} \cdot \frac{1+\sqrt{2}}{1+\sqrt{2}} = \frac{(23-24\sqrt{2})(1+\sqrt{2})}{(1-\sqrt{2})(1+\sqrt{2})} \]
\[ (23-24\sqrt{2})(1+\sqrt{2}) = 23 \cdot 1 + 23 \cdot \sqrt{2} - 24\sqrt{2} \cdot 1 - 24\sqrt{2} \cdot \sqrt{2} \]
\[ = 23 + 23\sqrt{2} - 24\sqrt{2} - 24 \cdot 2 \]
\[ = 23 - \sqrt{2} - 48 \]
\[ = -25 - \sqrt{2} \]
\[ (1-\sqrt{2})(1+\sqrt{2}) = 1^2 - (\sqrt{2})^2 = 1 - 2 = -1 \]
\[ \frac{-25-\sqrt{2}}{-1} = 25+\sqrt{2} \]
Ответ: 25+√2
