2[(4×5)−(4×3)]=2×[20−(4×3)]=2×[(20−12)]=2×8=16
$$\mathrm{2}\left[\left(\mathrm{4}×\mathrm{5}\right)−\left(\mathrm{4}×\mathrm{3}\right)\right]=\mathrm{2}×\left[\mathrm{20}−\left(\mathrm{4}×\mathrm{3}\right)\right]=\mathrm{2}×\left[\left(\mathrm{20}−\mathrm{12}\right)\right]=\mathrm{2}×\mathrm{8}=\mathrm{16} \\ $$
