\[\boxed{\text{167\ (167).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]

\[1)\ 3\sqrt{98}\ \ \ и\ \ 4\sqrt{72}\]

\[3 \cdot 7\sqrt{2}\ \ и\ \ 4 \cdot 6\sqrt{2}\]

\[21\sqrt{2} < 24\sqrt{2}\text{\ \ }\]

\[3\sqrt{98} < 4\sqrt{72}\]

\[2)\frac{1}{2}\sqrt{68}\ \ \ и\ \frac{4}{3}\sqrt{45}\]

\[\sqrt{17}\ \ \ и\ \ 4\sqrt{5}\]

\[\sqrt{17} < \sqrt{80}\text{\ \ }\]

\[\frac{1}{2}\sqrt{68} < \frac{4}{3}\sqrt{45}\]

\[3)\frac{1}{6}\sqrt{108}\text{\ \ \ }и\ \ 6\sqrt{\frac{1}{12}}\]

\[\sqrt{3}\ \ и\ \ \sqrt{\frac{36}{12}}\]

\[\sqrt{3} = \sqrt{3}\text{\ \ }\]

\[\frac{1}{6}\sqrt{108} = 6\sqrt{\frac{1}{12}}\]
