I don't think the solution should be independent of $c$. Maybe you typed into Wolfram

$$\ln a=- \ln b$$

between lists (n-uples), row vectors and column vectorsand thus the choice is a matter of convenience.
In linear algebra the column notation is more common because more conforming to the way we write
