Question

45768/1488 log.Plese answer clearly with steps.​

Answer 1

It is neither of them it is R-{1} cause are use to write log (x-1)^2 as 2 log (x-1) but actually it is 2 log |x-1| And I reduced 1 from R cause if we put 1 it comes 0 but we know the argument of a logorith should be greater than 0
