$\sqrt{2} * \sqrt{8} = \sqrt{2 * 8} = \sqrt{2 * 2 * 4} = \sqrt{4} * (\sqrt{2})^2 = 2 * 2 = 4$
$\sqrt{27} * \sqrt{3} = \sqrt{27 * 3} = \sqrt{3 * 9 * 3} = \sqrt{9} * (\sqrt{3})^2 = 3 * 3 = 9$
$\sqrt{28} * \sqrt{7} = \sqrt{28 * 7} = \sqrt{4 * 7 * 7} = \sqrt{4} * (\sqrt{7})^2 = 2 * 7 = 14$
$\sqrt{2} * \sqrt{32} = \sqrt{2 * 2 * 16} = \sqrt{16} * (\sqrt{2})^2 = 4 * 2 = 8$
$\sqrt{13} * \sqrt{52} = \sqrt{13 * 4 * 13} = \sqrt{4} * (\sqrt{13})^2 = 2 * 13 = 26$
$\sqrt{63} * \sqrt{7} = \sqrt{7 * 9 * 7} = \sqrt{9} * (\sqrt{7})^2 = 3 * 7 = 21$
$\sqrt{50} * \sqrt{4,5} = \sqrt{25 * 2 * \frac{9}{2}} = 5 * 3 = 15$
$\sqrt{1,2} * \sqrt{3\frac{1}{3}} = \sqrt{\frac{12}{10} * \frac{10}{3}} = \sqrt{4} = 2$
