what properties or rules are used to arrive at this answer?

two log rules:

log (A^n) = n logA
log(A/B) = logA - logB

your last line has mismatched brackets, should be
ln( (2x-1)^(1/2) / (x+1)^2) )

you can always check: then number of "(" brackets must be the same
as the number of ")" brackets in your expression or equation
