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
what properties or rules are used to arrive at this answer?
1/2ln(2x-1)-2ln(x+1)
=
ln((2x-1)^1/2/(x+1)^2)
