Assuming that you have those lines in a file called numbers.txt, you can
execute the following (all on one line):
cat numbers.txt | tr '.,e' ',^^' | awk -F^ '{printf("%s & $%s \\cdot
10^{%s}$\\\\\n", $1, $2, $3);}'
The output will be:
1,1 & $3,19 \cdot 10^{-4}$\\
1,2 & $3,05 \cdot 10^{-3}$\\
10,5 & $9,14 \cdot 10^{8}$\\
Not the most elegant solution, but it works. I hope this is what you were
looking for.
