[tex] \sqrt{3} + 3\sqrt{3} = 4 \sqrt{3} \\ 2 \sqrt{6} \times 4 = 8 \sqrt{6} \\ 5 \sqrt{3} + 4 - 2 \sqrt{3} = 3 \sqrt{3} + 4 \\ 6 \sqrt{2} \times 3 \sqrt{2} = 18 \times 2 = 36[/tex]
[tex]4 \sqrt{5} + \sqrt{5} = 5 \sqrt{5} \\ 6 \sqrt{2} - 4 \sqrt{2} = 2 \sqrt{2} \\ 3 \sqrt{6} + 5 - 2 \sqrt{6} + 7 = \sqrt{6} + 12 \\ 5 \sqrt{3 } - 2 \sqrt{3} = 3 \sqrt{3} [/tex]
[tex]6 \sqrt{3} \times 4 = 24 \sqrt{3} \\ 5 \sqrt{2} \times 2 \sqrt{3} = 10 \sqrt{6} [/tex]
