$$\sqrt{11}\cdot(\sqrt{3}-\sqrt{10})=\sqrt{33}-\sqrt{110}$$
Explanation
| $$ \begin{aligned}\sqrt{11}\cdot(\sqrt{3}-\sqrt{10})& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\sqrt{33}-\sqrt{110}\end{aligned} $$ | |
| ① | $$ \color{blue}{ \sqrt{11} } \cdot \left( \sqrt{3}- \sqrt{10}\right) = \color{blue}{ \sqrt{11}} \cdot \sqrt{3}+\color{blue}{ \sqrt{11}} \cdot- \sqrt{10} = \\ = \sqrt{33}- \sqrt{110} $$ |
