$a)\:28,4:\underline{10^2}+10\times[16,8-(\underline{400:100}-4)]=\\=\underline{28,4:100}+10\times[\underline{16,8-(4-4)}]=\\=0,284+\underline{10\times16,8}=\\=0,284+168=\\=\bf\red{168,284}$

$b)\:124,5\times(\underline{7,82:10}-0,54)-\underline{2,4^2}=\\=124,5\times(\underline{0,782-0,54})-5,76=\\=\underline{124,5\times0,242}-5,76=\\=30,129-5,76=\\=\bf\red{24,369}$
