Answer 1

$\displaystyle\bf\\1)\\\\\sqrt{12(3-\sqrt{10} )^{2} } =\sqrt{2^{2}\cdot 3\cdot (3-\sqrt{10} )^{2} } =2\sqrt{3} (\sqrt{10} -3)\\\\2)\\\\\Bigg(\frac{7}{6}\Bigg)^{-4} = \Bigg(\frac{6}{7}\Bigg)^{4} \\\\\\\Bigg(\frac{6}{7}\Bigg)^{-4} = \Bigg(\frac{7}{6}\Bigg)^{4} \\\\\\\Bigg(\frac{6}{7}\Bigg)^{4} \ \ \ ; \ \ \ \ \frac{7}{6} \ \ \ ; \ \ \ \Bigg(\frac{7}{6}\Bigg)^{4}$

$\displaystyle\bf\\Otvet \ : \ \Bigg(\frac{7}{6}\Bigg)^{-4} \ \ \ ; \ \ \ \ \frac{7}{6} \ \ \ ; \ \ \ \Bigg(\frac{6}{7}\Bigg)^{-4}$
