[tex] \sqrt[4]{ {2}^{3} } \times {8}^{ - 1 \frac{1}{3} } \times {( \sqrt[3]{16}) }^{ \frac{3}{2} } = {2}^{ \frac{3}{4} } \times {( {2}^{3}) }^{ - \frac{4}{3} } \times { ({2}^{ \frac{4}{3} } )}^{ \frac{3}{2} } = {2}^{ \frac{3}{4} } \times {2}^{ - 4 } \times {2}^{2} = {2}^{ - 1 \frac{1}{4} } [/tex]
[tex] { (\frac{1}{27} )}^{ \frac{1}{4} } \div { (\sqrt[5]{81}) }^{ - 3} \times {3}^{2} = { ({3}^{ - 3} )}^{ \frac{1}{4} } \div {( {3}^{ \frac{4}{5} }) }^{ - 3} \times {3}^{2} = {3}^{ - \frac{3}{4} } \div {3}^{ - \frac{12}{5} } \times {3}^{2} = {3}^{3 \frac{13}{20} } [/tex]
