Answer 2

Răspuns:

    $\frac{2\sqrt{3}}{15}$

Explicație pas cu pas:

    $\frac{1}{\sqrt{12}}+\frac{1}{\sqrt{75}}-\frac{3}{10\sqrt{3}}$

    $\frac{1}{2\sqrt{3}}+\frac{1}{5\sqrt{3}}-\frac{3}{10\sqrt{3}}$

    $\frac{\sqrt{3}}{6}+\frac{\sqrt{3}}{15}-\frac{3\sqrt{3}}{30}$

    $\frac{5\sqrt{3}}{30}+\frac{2\sqrt{3}}{30}-\frac{3\sqrt{3}}{30}$

    $\frac{4\sqrt{3}}{30}$ = $\frac{2\sqrt{3}}{15}$
