Explanation
| $$ \begin{aligned}\frac{\sqrt{120}\cdot\sqrt{3}}{3}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\frac{6\sqrt{10}}{3} \xlongequal{ } \\[1 em] & \xlongequal{ }2\sqrt{10}\end{aligned} $$ | |
| ① | $$ \sqrt{360} =
\sqrt{ 6 ^2 \cdot 10 } =
\sqrt{ 6 ^2 } \, \sqrt{ 10 } =
6 \sqrt{ 10 }$$ |
