[tex]a) (\sqrt{7} )^{2} + (\sqrt{8} )^{2} =7+8=15\\[/tex]
[tex]b) \sqrt[3]{5^{3} } - \sqrt[3]{6^{3} } = 5 - 6 =-1\\[/tex]
[tex]c) (\sqrt[3]{15})^{3} +(\sqrt{15} )^{2} =15+15 =30\\[/tex]
[tex]d)(\sqrt[3]{19})^{3} - (\sqrt[3]{\frac{1}{2} })^{3} * (\sqrt[3]{24})^{3} = 19-\frac{1}{2} *24 = 19 - 12 = 7\\[/tex]
[tex]e)\frac{(\sqrt{2} )^{2} + (\sqrt{18} )^{2} }{(\sqrt[3]{15})^{3} - (\sqrt[3]{35})^{3}} = \frac{2+18}{15-35} = \frac{20}{-20}=-1[/tex]
