a) [tex]5(\sqrt{3} - 4) + \sqrt{3}(6+2\sqrt{3}) = 5\sqrt{3} - 20 + 6\sqrt{3} + 6 = 11\sqrt{3} - 14[/tex]
b) [tex]2\sqrt{6}(2+5\sqrt{6}) - 3(5 - 4\sqrt{6}) = 4\sqrt{6} + 60 - 15 + 12\sqrt{6} = 16\sqrt{6}+ 45[/tex]
c) [tex]4\sqrt{2}(5\sqrt{2} - 6) + 3\sqrt{2}(7-4\sqrt{2}) = 40-24\sqrt{2} + 21\sqrt{2}-24 = 16-3\sqrt{2}[/tex]
d) [tex]5(3+2\sqrt[3]{7}-4) = 5(-1 + 2\sqrt[3]{7}) = -5 + 10\sqrt[3]{7}[/tex]
