=(4^(−3) ×5^(−3) )^(−(1/3)) =(20^(−3) )^(−(1/3)) =20^(−3×(−(1/3))) =20
$$=\left(\mathrm{4}^{−\mathrm{3}} ×\mathrm{5}^{−\mathrm{3}} \right)^{−\frac{\mathrm{1}}{\mathrm{3}}} =\left(\mathrm{20}^{−\mathrm{3}} \right)^{−\frac{\mathrm{1}}{\mathrm{3}}} =\mathrm{20}^{−\mathrm{3}×\left(−\frac{\mathrm{1}}{\mathrm{3}}\right)} =\mathrm{20} \\ $$
