9. Вычислите: $$10 \cdot \sqrt{1 \frac{11}{25}} + 9(\sqrt{8})^2 + (\frac{1}{5} \cdot \sqrt{125})^2$$

$$10 \cdot \sqrt{1 \frac{11}{25}} + 9(\sqrt{8})^2 + (\frac{1}{5} \cdot \sqrt{125})^2 = 10 \cdot \sqrt{\frac{36}{25}} + 9 \cdot 8 + (\frac{1}{5} \cdot \sqrt{25 \cdot 5})^2 = 10 \cdot \frac{6}{5} + 72 + (\frac{1}{5} \cdot 5 \sqrt{5})^2 = 12 + 72 + (\sqrt{5})^2 = 12 + 72 + 5 = 89$$

Ответ: 89
