Question

Помогите решить пример, упрощая

Answer 1

$\frac{2*5}{4*5^2-10*5*\sqrt{3}} - \frac{5\sqrt{3}}{4*5^2-25*3}=\\ \frac{10}{100-50\sqrt{3}}-\frac{5\sqrt{3}}{100-75}=\\ \frac{1}{5(2-\sqrt{3})}-\frac{\sqrt{3}}{5}=\\ \frac{1-\sqrt{3}(2-\sqrt{3})}{5(2-\sqrt{3})}=\\ \frac{2(2-\sqrt{3})}{5(2-\sqrt{3})}=\frac{2}{5}$
