\[\boxed{\mathbf{238\ (238)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]
Пояснение.
Решение.
\[\frac{5^{\backslash 8}}{6} = \frac{40}{48};\ \ \ \ \ \frac{5^{\backslash 6}}{8} = \frac{30}{48};\ \ \ \frac{7^{\backslash 3}}{16} =\]
\[= \frac{21}{48};\ \ \ \ \frac{9^{\backslash 2}}{24} = \frac{18}{48};\ \ \ \ \]
\[\frac{10^{\backslash 4}}{12} = \frac{40}{48};\ \ \ \ \frac{10^{\backslash 16}}{3} = \frac{160}{48};\ \]
\[\text{\ \ \ }\frac{5^{\backslash 12}}{4} = \frac{60}{48}\]
