9. (3\(\sqrt{75}\) - 2\(\sqrt{48}\)) : \(\sqrt{3}\)

9. (3\(\sqrt{75}\) - 2\(\sqrt{48}\)) : \(\sqrt{3}\) = (3\(\sqrt{25 \cdot 3}\) - 2\(\sqrt{16 \cdot 3}\)) : \(\sqrt{3}\) = (3 \cdot 5\(\sqrt{3}\) - 2 \cdot 4\(\sqrt{3}\)) : \(\sqrt{3}\) = (15\(\sqrt{3}\) - 8\(\sqrt{3}\)) : \(\sqrt{3}\) = 7\(\sqrt{3}\) : \(\sqrt{3}\) = 7
