Ответ:
Перемножаем подкоренные числа и упрощаем корень: \(\sqrt m\cdot\sqrt n=\sqrt{mn}\).
| × | \(\sqrt1\) | \(\sqrt2\) | \(\sqrt3\) | \(\sqrt4\) | \(\sqrt5\) | \(\sqrt6\) |
|---|---|---|---|---|---|---|
| \(\sqrt1\) | 1 | \(\sqrt2\) | \(\sqrt3\) | 2 | \(\sqrt5\) | \(\sqrt6\) |
| \(\sqrt2\) | \(\sqrt2\) | 2 | \(\sqrt6\) | \(2\sqrt2\) | \(\sqrt{10}\) | \(2\sqrt3\) |
| \(\sqrt3\) | \(\sqrt3\) | \(\sqrt6\) | 3 | \(2\sqrt3\) | \(\sqrt{15}\) | \(3\sqrt2\) |
| \(\sqrt4\) | 2 | \(2\sqrt2\) | \(2\sqrt3\) | 4 | \(2\sqrt5\) | \(2\sqrt6\) |
