Answer 1

Ответ:

$\sqrt{2} + \sqrt{4 \times 2} - \sqrt{9 \times 2} = \sqrt{2} + 2 \sqrt{2} - 3 \sqrt{2} = \\ \sqrt{3} + \sqrt{4 \times 3} - \sqrt{16 \times 3} = \sqrt{3} + 2 \sqrt{ 3} - 4 \sqrt{3} = \\ \sqrt{9 \times 2} + \sqrt{25 \times 2} - \sqrt{49 \times 2} = 3 \sqrt{2} + 5 \sqrt{2} - 7 \sqrt{2 } =$
