Question

помогите пожалуйста номер 74 плизз срочно надо

Answer 1

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