Question

Помогите решить номер самый первый 3.7

Answer 1

$\sqrt{\frac{7}{11}}=\frac{\sqrt{7}}{\sqrt{11}}\\\\\sqrt{\frac{a}{17}}=\frac{\sqrt{a}}{\sqrt{17}}\\\\\sqrt{\frac{5}{c}}=\frac{\sqrt{5}}{\sqrt{c}} \\\\\sqrt{\frac{y}{131}}=\frac{\sqrt{y}}{\sqrt{131}}$

$\sqrt{\frac{5}{47c}}=\frac{\sqrt{5}}{\sqrt{47c}}\\\\\sqrt{\frac{2y}{231}} =\frac{\sqrt{2y}}{\sqrt{231}}$

$\sqrt{\frac{15}{57a}}=\frac{\sqrt{15}}{\sqrt{57}} \\\\\sqrt{\frac{21y}{56}}=\frac{\sqrt{2y}}{\sqrt{56}}$
