Question

помогите пожалуйста номер 74 плизз срочно надо

Answer 1

$\frac{\sqrt{3}\sqrt{3+\sqrt{3}}\sqrt{3-\sqrt{3}}}{\sqrt{2\sqrt{3}}} = \frac{\sqrt{3(3+\sqrt{3})(3-\sqrt{3})}}{\sqrt{2\sqrt{3}}} = \sqrt{\frac{3(9-3)}{2\sqrt{3}}} = \sqrt{\frac{3*6}{2\sqrt{3}} }= \sqrt{\frac{9}{\sqrt{3}}} = \sqrt{\frac{9\sqrt{3}}{3}} = \sqrt{3\sqrt{3}} = \sqrt{\sqrt{27}} = \sqrt[4]{27}$
