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 = 64 - 3 \sqrt{2} [/tex]
d)
[tex]5(3 + 2\sqrt[3]{7} ) - 2(3 \sqrt[3]{7} - 4) = 15 + 10 \sqrt[3]{7} - 6 \sqrt[3]{7} + 8 = 23 + 4 \sqrt[3]{7} [/tex]
