    $(5^{4}+$ $4^{7}).($ $2^{4}-$ $4^{2}).($ $2021^{3}-$ $2019^{2})$
    $=$ $(5^{4}.$ $4^{7}).(16-16).($ $2021^{3}-$ $2019^{2})$
    $=$ $(5^{4}.$ $4^{7}).0.($ $2021^{3}-$ $2019^{2})$
    $=0$

    Answer
    (5^{4} . 4^{7}) . (2^{4} – 4^{2}) . (2021^{3} – 2019^{2})
    = (5^{4} . 4^{7}) . (16 – 16) . (2021^{3} – 2019^{2})
    = (5^{4} . 4^{7}) . 0 . (2021^{3} – 2019^{2})
     = 0
