    Simplify $${\left( {\frac{{2{m^3}{n^2}}}{{3m{n^5}}}} \right)^3} \times \frac{{6{m^2}{n^4}}}{{4{m^3}{n^{10}}}}$$

    $$ = \frac{{8{m^9}{n^6}}}{{27{m^3}{n^{15}}}} \times \frac{{6{m^2}{n^4}}}{{4{m^3}{n^{10}}}}$$

    $$ = \frac{{4{m^{11}}{n^{10}}}}{{9{m^6}{n^{25}}}}$$

    $$ = \frac{{4{m^5}}}{{9{n^{15}}}}$$

    Simplify $$\frac{{7{a^2}b^4}}{{3{a^6}{b^7}}} \div {\left( {\frac{{3ab}}{{2{a^6}{b^4}}}} \right)^3}$$

    $$\frac{7}{{3{a^4}{b^3}}} \div \frac{{27{a^3}{b^3}}}{{8{a^{18}}{b^{12}}}}$$

    $$ = \frac{7}{{3{a^4}{b^3}}} \times \frac{{8{a^{18}}{b^{12}}}}{{27{a^3}{b^3}}}$$

    $$ = \frac{7}{{3{a^4}{b^3}}} \times \frac{{8{a^{15}}{b^9}}}{{27}}$$

    $$=\frac{{56{a^{11}}{b^6}}}{{81}}$$

    Simplify $$\frac{{6{x^{\frac{3}{2}}}{y^{\frac{1}{2}}} \times {x^{\frac{4}{5}y\frac{3}{5}}}}}{{2{{\left( {{x^{\frac{1}{2}}}y} \right)}^{\frac{1}{5}}} \times 3{x^{\frac{1}{2}}}{y^{\frac{1}{5}}}}}$$

    $$ = \frac{{6{x^{\frac{{23}}{{10}}}}{y^{\frac{{11}}{{10}}}}}}{{6{x^{\frac{1}{{10}}}}{y^{\frac{1}{5}}} \times {x^{\frac{1}{2}}}{y^{\frac{1}{5}}}}}$$

    $$ = \frac{{{x^{\frac{{23}}{{10}}}}{y^{\frac{{11}}{{10}}}}}}{{{x^{\frac{3}{5}}}{y^{\frac{2}{5}}}}}$$

    $$ = {x^{\frac{{17}}{{10}}}}{y^{\frac{7}{{10}}}}$$
