Answer 1

$1)7^{\frac{5}{11} }=\sqrt[11]{7^{5} }\\\\c^{-\frac{3}{5}}=\frac{1}{\sqrt[5]{c^{3}}}\\\\3^{1,6}=3^{\frac{8}{5}}=\sqrt[5]{3^{8}}\\\\\\2)\sqrt[3]{7^{2} }=7^{\frac{2}{3}} \\\\\sqrt[12]{x^{-11}} =x^{-\frac{11}{12} } \\\\\\3)a^{\frac{2}{5}}*a^{\frac{1}{2}}:a^{\frac{1}{10}} =a^{\frac{2}{5}+\frac{1}{2}-\frac{1}{10}}=a^{\frac{4}{10}+\frac{5}{10}-\frac{1}{10}}=a^{\frac{8}{10}}\\\\(x^{\frac{2}{11}} )^{3} *x^{\frac{5}{11}}=x^{\frac{6}{11}}*x^{\frac{5}{11}}=x^{\frac{6}{11}+\frac{5}{11}}=x$

$(c^{-\frac{5}{11}} *y^{-0,5})^{4}*c*y^{4,6}=c^{-\frac{20}{11}} *y^{-2}*c*y^{4,6}=c^{-\frac{20}{11}+1}*y^{-2+4,6}=c^{-\frac{9}{11} }y^{2,6}$
