Помогите пожалуйста решить 72-73

[latex] \sqrt{ \frac{27}{32} } = \sqrt{ \frac{9*3}{16*2}} = \frac{3 \sqrt{3} }{4 \sqrt{2} } [/latex] [latex] \sqrt{ \frac{64}{99}} = \sqrt{ \frac{64}{9*11}} = \frac{8}{3 \sqrt{11} } [/latex] [latex] \sqrt{ \frac{242}{225}} = \sqrt{ \frac{121*2}{225}} = \frac{11 \sqrt{2} }{15} [/latex] [latex] \sqrt{10 \frac{1}{12}} = \sqrt{ \frac{121}{4*3}} = \frac{11}{ 2\sqrt{3} } [/latex] [latex] \sqrt{ 3\frac{19}{50}} = \sqrt{ \frac{169}{25*2}} = \frac{13}{5 \sqrt{2} } [/latex]
