Answer 1

$\sqrt{8} *\sqrt{(2\sqrt{3} -3)^2} -\sqrt{(5\sqrt{2}-3\sqrt{6} )^2 } =\\2\sqrt{2} *\sqrt{(2\sqrt{3} -3)^2} -\sqrt{(5\sqrt{2} -3\sqrt{6})^2 } =\\2\sqrt{2} *(|2\sqrt{3} -3|)-\sqrt{5\sqrt{2}-3\sqrt{6})^2 } =\\2\sqrt{2} *(2\sqrt{3} -3)-|5\sqrt{2} -3\sqrt{6} |=\\2\sqrt{2} *(2\sqrt{3} -3)-(3\sqrt{6} -5\sqrt{2} )=\\4\sqrt{6} -6\sqrt{2} -(3\sqrt{6} -5\sqrt{2})=\\4\sqrt{6} -6\sqrt{2} -3\sqrt{6} +5\sqrt{2} =\\4\sqrt{6} -3\sqrt{6} -6\sqrt{2} +5\sqrt{2} =\\1\sqrt{6} -1\sqrt{2} =\\\sqrt{6} -\sqrt{2}$
