[tex]a) \ \sqrt{121} = \sqrt{11^{2}} = 11\\\\\\b) \ \sqrt{\frac{36}{169}}=\frac{\sqrt{36}}{\sqrt{169}} = \frac{\sqrt{6^{2}}}{\sqrt{13^{2}}}=\frac{6}{13}\\\\\\c) \ \sqrt[3]{-125} = \sqrt[3]{(-5)^{3}} = -5[/tex]
[tex]d) \ \sqrt[3]{3\frac{3}{8}} = \sqrt[3]{\frac{27}{8}}=\frac{\sqrt[3]{27}}{\sqrt[3]{8}} = \frac{\sqrt[3]{3^{3}}}{\sqrt[3]{2^{3}}} = \frac{3}{2} =1\frac{1}{2}[/tex]
