$( {{2}^{8} \times {5}^{ - 5} \times {19}^{0} })^{ - 2} \times ({{5}^{ - 2} \div {2}^{3} ) }^{4} \times {2}^{28} \\ \\ {2}^{(8)( - 2)} \times {5}^{( - 5)( - 2)} \times {19}^{(0)( - 2)} \times ( {5}^{( - 2)(4) } \div {2}^{(3)(4)} ) \times {2}^{28} \\ \\ those \: with \: same \: base \: add \: their \: powers \\$ now,you have an equation wich looks like this2^(-16) ×2^(28)×2^(-8)× 5^(10)×5^(-8)×1 =2^(-16+28-8) ×5^(10-8 ) = 2^(4)×5^(2) =400.
