Question 1064213
.
No one of A) - E) is equivalent.


Because the given equation has the domain {all real numbers}.


The equations A) - E) have the domain (domains) {all real positive numbers}.


For example, the pair x= -1, y= -7 is the solution to the given equation. Agree?


Now check if this pair does suit to any of the equations A) - E), and everything will become clear to you (I hope).


I just answered this question before.
