Найдите значение выражения
$( \sqrt[4]3} - \sqrt[4]{27} ) ^{2} : (6- 4\sqrt[]{3})$

Answer 1

$( \sqrt[4]{3} - \sqrt[4]{27} )^{2} / (6 - 4 \sqrt{3} ) \\ \frac {(\sqrt[4]{3}- \sqrt[4]{27} )^2}{6-4 \sqrt{3}} \\ \frac {\sqrt {3} - 6 + \sqrt {27} }{6-4\sqrt {3}} \\ \frac {\sqrt {3} - 6 +3 \sqrt {3} }{6-4\sqrt {3}} \\ \frac {4\sqrt {3}-6}{6-4\sqrt {3}} \\ \frac {-(6-4\sqrt {3})}{6-4\sqrt {3}} =-1$
