\(\sqrt{75}-\sqrt{5\frac{1}{3}}+\frac{9}{2}\sqrt{2\frac{2}{3}}+2\sqrt{27}\)
= \(5\sqrt{3}\) - \(\frac{4\sqrt{3}}{3}\) + \(3\sqrt{2}\sqrt{3}\) + \(6\sqrt{3}\)
= \(\frac{15\sqrt{3}-4\sqrt{3}+9\sqrt{2}\sqrt{3}+18\sqrt{3}}{3}\)
= \(\frac{\sqrt{3}\left(29+9\sqrt{2}\right)}{3}\) = \(\frac{9\sqrt{6}+29\sqrt{3}}{3}\)
