Question 191140
<font face="Garamond" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  4\,\cdot\,\sqrt{10}\,\cdot\,3\,\cdot\,\sqrt{6}\ =\ 12\,\cdot\,\sqrt{10}\sqrt{6}\ =\ 12\,\cdot\,\sqrt{60}]


But *[tex \LARGE 60\ =\ 4 \times 15] so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 12\,\cdot\,\sqrt{60}\ =\ 12\,\cdot\,\sqrt{4}\sqrt{15}\ =\ 12\,\cdot\,2\,\cdot\,\sqrt{15}\ =\ 24\,\cdot\,\sqrt{15}]
