Answer: False

=============================================================

Step-by-step explanation:

The radical is one step away from being fully isolated. We would apply the rule that
(√(A))/(√(B)) = \sqrt{(A)/(B)}

In this case,


(√(x+3))/(√(x-1)) = \sqrt{(x+3)/(x-1)}

Meaning that the equation


(√(x+3))/(√(x-1)) =3

is the same as


\sqrt{(x+3)/(x-1)} = 3

From here, we square both sides and use algebra to isolate x.
