$${{\mathtt{10}}}^{-{\mathtt{3}}}$$ ist ja $${\frac{{\mathtt{1}}}{\left({{\mathtt{10}}}^{{\mathtt{3}}}\right)}}$$
und 1/ $${\frac{{\mathtt{1}}}{{{\mathtt{10}}}^{{\mathtt{3}}}}}$$ ist $${{\mathtt{10}}}^{{\mathtt{3}}}$$
also ist $${\frac{{\mathtt{1}}}{\left({\mathtt{2}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{3}}}\right)}}$$ das Gleiche wie $${\frac{{{\mathtt{10}}}^{{\mathtt{3}}}}{{\mathtt{2}}}}$$

$${\frac{{\mathtt{1}}}{\left({\mathtt{2}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{\left(-{\mathtt{3}}\right)}\right)}} = {\mathtt{500}}$$
$${{\mathtt{10}}}^{\left(-{\mathtt{3}}\right)} = {\frac{{\mathtt{1}}}{{\mathtt{1\,000}}}} = {\mathtt{0.001}}$$
$${\frac{{\mathtt{1}}}{{{\mathtt{10}}}^{\left(-{\mathtt{3}}\right)}}} = {\mathtt{1\,000}}$$
