in both of my intro calc books, ln was defined as the integral of 1/t
from 1 to x. so this follows immediately from this definition and the
Fundamental Theorem.
there are, of course, other, equally valid, ways to define ln(x) and
exp(x); they all lead to the same results.

geometry is poorly taught, unfortunately. they should start with
finite incidence geometries before introducing Euclidean geometry.
but this is getting _very_ far off topic.
