Answer 1

$\displaystyle\bf\\4\sqrt{3\frac{1}{2} }-0,5\sqrt{56} -3\sqrt{1\frac{5}{9} } =4\sqrt{\frac{7}{2} } -0,5\sqrt{4\cdot14} -3\sqrt{\frac{14}{9} } =\\\\\\=4\sqrt{\frac{7}{2} }-0,5\cdot2\cdot\sqrt{14} -3\cdot\frac{1}{3} \cdot\sqrt{14}=2\sqrt{2} \cdot\sqrt{14}-\sqrt{14}-\sqrt{14}=\\\\\\=2\sqrt{2} \cdot\sqrt{14} -2\sqrt{14}=2\sqrt{14} (\sqrt{2} -1)$
