Answer 1

$\sqrt{(\sqrt{3}-\sqrt{7})^{2} } +\sqrt{(\sqrt{3}+\sqrt{7})^{2} }=\\=\sqrt{7} -\sqrt{3} +\sqrt{7} -\sqrt{3}=\\2\sqrt{7} -2\sqrt{3}$

$\sqrt[3]{8+12+12\sqrt{2}+2\sqrt{2}}+\sqrt[3]{8+12-12\2+\sqrt{2}-2\sqrt{2}}=\\\sqrt[3]{(2+\sqrt{2} )^{3} } +\sqrt[3]{(2-\sqrt{2} )^{3} } =2+\sqrt{12} +2-\sqrt{2} =\\2+2=4$
