[tex]\sqrt{\frac{64}{81}} = \frac{\sqrt{64}}{\sqrt{81}} =\frac{\sqrt{8^{2}}}{\sqrt{9^{2}}}=\frac{8}{9}\\\\\\\sqrt{0,0144} = 0,12\\\\\\\sqrt{3\frac{1}{16}} = \sqrt{\frac{49}{16} } = \frac{\sqrt{49}}{\sqrt{16}} = \frac{7}{4} = 1\frac{3}{4}\\\\\\\sqrt[3]{125000} = 50\\\\\\\sqrt[3]{\frac{27}{64}} = \frac{\sqrt[3]{27}}{\sqrt[3]{64}} = \frac{3}{4}\\\\\\\sqrt[3]{-3\frac{3}{8}} = \sqrt[3]{-\frac{27}{8}} = \sqrt[3]{(-\frac{3}{2})^{3}}} = -\frac{3}{2} = -1\frac{1}{2}[/tex]
