$5 \times | \sqrt{2} + 1| - 2 \times ( \frac{3}{ \sqrt{2} } - \frac{ \sqrt{6} }{ \sqrt{2} } + \frac{ \sqrt{2} }{ \sqrt{2} } ) - |2 \sqrt{2} - 3 | - 4 \sqrt{2} = \\ = 5 \times ( \sqrt{2} + 1) - 2 \times ( \frac{3 \sqrt{2} }{2} - \frac{ \sqrt{12} }{2} + \frac{ \sqrt{4} }{2} ) - ( - (2 \sqrt{2} - 3) - 4 \sqrt{2} = \\ = 5 \sqrt{2} + 5 - 2 \times ( \frac{3 \sqrt{2} - 2 \sqrt{3} + 2 }{2} ) - ( - 2 \sqrt{2} + 3) - 4 \sqrt{2} = \\ = 5 \sqrt{2} + 5 - 1 \times (3 \sqrt{2} - 2 \sqrt{3} + 2) + 2 \sqrt{2} - 3 - 4 \sqrt{2} = \\ = 5 \sqrt{2} + 5 - 3 \sqrt{2} + 2 \sqrt{3} - 2 + 2 \sqrt{2} - 3 - 4 \sqrt{2} = \\ = 2 \sqrt{3}$
