`\sqrt{9-3\sqrt{8}}-(\sqrt{3}-1)/\sqrt{2}+\sqrt{5-2\sqrt{6}}-\sqrt{2-\sqrt{3}}` 

`=\sqrt{(\sqrt{6})^2-2.\sqrt{6}.\sqrt{3}+(\sqrt{3})^2}-(\sqrt{3}-1)/\sqrt{2}-\sqrt{2-\sqrt{3}+\sqrt{(\sqrt{3})^2-2.\sqrt{3}.\sqrt{2}+(\sqrt{2})^2}`

`=\sqrt{(\sqrt{6}-\sqrt{3})^2}-(\sqrt{3}-1-\sqrt{4-2\sqrt{3}})/\sqrt{2}+\sqrt{(\sqrt{3}-\sqrt{2})^2}`

`=|\sqrt{6}-\sqrt{3}|-(\sqrt{3}-1-\sqrt{(\sqrt{3})^2-2.\sqrt{3}.1+1^2})/\sqrt{2}+|\sqrt{3}-\sqrt{2}|`

`=\sqrt{6}-\sqrt{3}-(\sqrt{3}-1-\sqrt{(\sqrt{3}-1)^2})/\sqrt{2}+\sqrt{3}-\sqrt{2}`

`=\sqrt{6}-\sqrt{2}-((\sqrt{3}-1)-(\sqrt{3}-1))/\sqrt{2}`

`=\sqrt{6}-\sqrt{2}-0/\sqrt{2}`

`=\sqrt{6}-\sqrt{2}` 

Vậy `...`
