Решение:
Необходимо найти значения иррациональных выражений.
- \( \sqrt{75} \cdot \sqrt{3} = \sqrt{75 \cdot 3} = \sqrt{225} = 15 \)
- \( \sqrt{44} \cdot \sqrt{11} = \sqrt{44 \cdot 11} = \sqrt{484} = 22 \)
- \( \sqrt{1.4} \cdot \sqrt{35} = \sqrt{1.4 \cdot 35} = \sqrt{49} = 7 \)
- \( \sqrt{30} \cdot \sqrt{1.2} = \sqrt{30 \cdot 1.2} = \sqrt{36} = 6 \)
- \( \frac{\sqrt{180}}{\sqrt{5}} = \sqrt{\frac{180}{5}} = \sqrt{36} = 6 \)
- \( \frac{\sqrt{392}}{\sqrt{8}} = \sqrt{\frac{392}{8}} = \sqrt{49} = 7 \)
- \( \frac{4\sqrt{48}}{\sqrt{3}} = 4\sqrt{\frac{48}{3}} = 4\sqrt{16} = 4 \cdot 4 = 16 \)
- \( \frac{7\sqrt{50}}{\sqrt{2}} = 7\sqrt{\frac{50}{2}} = 7\sqrt{25} = 7 \cdot 5 = 35 \)
- \( \frac{\sqrt{252}}{2\sqrt{7}} = \frac{1}{2} \sqrt{\frac{252}{7}} = \frac{1}{2} \sqrt{36} = \frac{1}{2} \cdot 6 = 3 \)
- \( \frac{\sqrt{275}}{10\sqrt{11}} = \frac{1}{10} \sqrt{\frac{275}{11}} = \frac{1}{10} \sqrt{25} = \frac{1}{10} \cdot 5 = 0.5 \)
- \( (8\sqrt{3})^2 \)
\( = 8^2 \cdot (\sqrt{3})^2 = 64 \cdot 3 = 192 \) - \( \frac{(4\sqrt{5})^2}{20} = \frac{4^2 \cdot (\sqrt{5})^2}{20} = \frac{16 \cdot 5}{20} = \frac{80}{20} = 4 \)
- \( \frac{39}{(2\sqrt{13})^2} = \frac{39}{2^2 \cdot (\sqrt{13})^2} = \frac{39}{4 \cdot 13} = \frac{39}{52} = \frac{3}{4} = 0.75 \)
