Answer 1

$\frac{8^{4}.0,00000064. \frac{1}{4} }{2^{-2}.4^{8}.256^{-1}.0,01024} \\ \\ \frac{8^{4}.0,00000016}{2^{-2}.2^{16}.2^{-8}. \frac{2^{10}}{10^{5}} } \\ \\ \frac{2^{12}. \frac{2^{4}}{10^{8}} }{2^{6}. \frac{2^{10}}{10^{5}} } \\ \\ \frac{2^{12}}{2^{6}}. \frac{2^{4}}{10^{8}}. \frac{10^{5}}{2^{10}} \\ \\ \frac{2^{12}}{2^{6}}. \frac{2^{4}}{2^{10}} . \frac{10^{5}}{10^{8}} \\ \\ 2^{6}.2^{-6}.10^{-3}= 2^{0}.10^{-3}=0,001$
