- \(\sqrt[3]{ (\frac{9}{10})^{6} }\\= (\frac{9}{10})^{\frac{6}{3}}\\= (\frac{9}{10})^{2}=\frac{81}{100}\)
- \(\sqrt[3]{ (\frac{1}{2})^{-9} }\\= (\frac{1}{2})^{\frac{-9}{3}}\\= (\frac{1}{2})^{-3}\\= (2)^{3}= 8\)
- \( \sqrt{ (\frac{1}{2})^{4} } \\= (\frac{1}{2})^{\frac{4}{2}}\\= (\frac{1}{2})^{2}=\frac{1}{4}\)
- \( \sqrt{ (\frac{3}{4})^{6} } \\= (\frac{3}{4})^{\frac{6}{2}}\\= (\frac{3}{4})^{3}=\frac{27}{64}\)
- \(\sqrt[9]{ (\frac{1}{8})^{3} }\\= (\frac{1}{8})^{\frac{-3}{9}}\\= (\frac{1}{8})^{\frac{-1}{3}}\\=\sqrt[3]{ 8 }=2\)
- \(\sqrt[4]{ (\frac{3}{4})^{12} }\\= (\frac{3}{4})^{\frac{12}{4}}\\= (\frac{3}{4})^{3}=\frac{27}{64}\)
- \(\sqrt[3]{ (\frac{2}{9})^{6} }\\= (\frac{2}{9})^{\frac{6}{3}}\\= (\frac{2}{9})^{2}=\frac{4}{81}\)
- \(\sqrt[3]{ (\frac{2}{3})^{12} }\\= (\frac{2}{3})^{\frac{12}{3}}\\= (\frac{2}{3})^{4}=\frac{16}{81}\)
- \(\sqrt[3]{ (\frac{3}{2})^{-12} }\\= (\frac{3}{2})^{\frac{-12}{3}}\\= (\frac{3}{2})^{-4}\\= (\frac{2}{3})^{4}= \frac{16}{81}\)
- \(\sqrt[8]{ (\frac{64}{81})^{4} }\\= (\frac{64}{81})^{\frac{4}{8}}\\= (\frac{64}{81})^{\frac{1}{2}}\\= \sqrt{ \frac{64}{81} } =\frac{8}{9}\)
- \(\sqrt[9]{ (\frac{27}{64})^{3} }\\= (\frac{27}{64})^{\frac{3}{9}}\\= (\frac{27}{64})^{\frac{1}{3}}\\=\sqrt[3]{ \frac{27}{64} }=\frac{3}{4}\)
- \(\sqrt[4]{ (4)^{2} }\\= (4)^{\frac{2}{4}}\\= (4)^{\frac{1}{2}}\\= \sqrt{ 4 } =2\)
