me ajudem galera!!!!!​

Answer 1

Precisa eliminar as vírgulas para começar transformando tudo em potência

de base 10 .

$\frac{10^{-3} . (0,001)^{-2}}{1000^{-4} } =\\\\\\ \frac{10^{-3}.(1.10^{-3})^{-2} }{1.10^{3}.10^{-4} } =\\\\\frac{10^{-3}.(1.10)^{-3.(-2)} }{1.10^{3.(-4)} } = \\\\\frac{10^{-3}.(1.10)^{6} }{1.10^{-12} } =\\\\\frac{10^{-3+6} }{10^{-122} } = \\\\\frac{10^{3} }{10^{-12} } = \\\\10^{3-12} =\\\\10^{-9}$
