81^(1/4) ×9^(3/2) ×27^(4/3)   =(9^2 )^(1/4) ×(3^2 )^(3/2) ×(3^3 )^(4/3)   =9^(1/2) ×(3^3 )×(3^4 )  =3×27×81  =6561
$$\mathrm{81}^{\frac{\mathrm{1}}{\mathrm{4}}} ×\mathrm{9}^{\frac{\mathrm{3}}{\mathrm{2}}} ×\mathrm{27}^{\frac{\mathrm{4}}{\mathrm{3}}} \\ $$$$=\left(\mathrm{9}^{\mathrm{2}} \right)^{\frac{\mathrm{1}}{\mathrm{4}}} ×\left(\mathrm{3}^{\mathrm{2}} \right)^{\frac{\mathrm{3}}{\mathrm{2}}} ×\left(\mathrm{3}^{\mathrm{3}} \right)^{\frac{\mathrm{4}}{\mathrm{3}}} \\ $$$$=\mathrm{9}^{\frac{\mathrm{1}}{\mathrm{2}}} ×\left(\mathrm{3}^{\mathrm{3}} \right)×\left(\mathrm{3}^{\mathrm{4}} \right) \\ $$$$=\mathrm{3}×\mathrm{27}×\mathrm{81} \\ $$$$=\mathrm{6561} \\ $$
