Explanation
| $$ \begin{aligned}\sqrt{2}\cdot(\sqrt{3}+5)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\sqrt{6}+5\sqrt{2}\end{aligned} $$ | |
| ① | $$ \color{blue}{ \sqrt{2} } \cdot \left( \sqrt{3} + 5\right) = \color{blue}{ \sqrt{2}} \cdot \sqrt{3}+\color{blue}{ \sqrt{2}} \cdot5 = \\ = \sqrt{6} + 5 \sqrt{2} $$ |
