Ответ:

$\frac{ \sqrt{18} }{ \sqrt{13} } = \sqrt{ \frac{18}{13} } = \sqrt{ \frac{3 {}^{2} 2}{13} } = 3 \sqrt{ \frac{2}{13} } = \frac{3 \sqrt{26} }{13} .$

NNNLLL54 после 3-го знака "=" должно быть : 3*sqrt(2/13)=3*sqrt(26/13^2)=3*sqrt(16)/13

Ответ:

$\displaystyle \frac{\sqrt{18}}{\sqrt{13}}=\frac{\sqrt{9\cdot 2}}{\sqrt{13}}=\frac{3\sqrt2}{\sqrt{13}}=\frac{3\sqrt2\cdot \sqrt{13}}{13}=\frac{3\sqrt{26}}{13}$
