find s value 0.002=S(5*10^-6)+(5*10^-12)*S^6(9.347*10^-6)*1095

$${\mathtt{0.002}} = {S}{\left({\mathtt{5}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{6}}}\right)}{\mathtt{\,\small\textbf+\,}}\left({\mathtt{5}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{12}}}\right){\mathtt{\,\times\,}}{{\mathtt{S}}}^{{\mathtt{6}}}{\mathtt{\,\times\,}}\left({\mathtt{9.347}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{6}}}\right){\mathtt{\,\times\,}}{\mathtt{1\,095}} \Rightarrow \left\{ \begin{array}{l}\end{array} \right\}$$

0.002/((5*10^-6)+(5*10^-12)*S^6(9.347*10^-6)*10950)=S

now you can do it on the site calc - it is on the home page.
