Problem 161 of 7
Identify extraneous or off-domain intersections from solving squaring both sides gives x=6, but substituting it back into the original radical equation results in an inequality.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Check each candidate in original functions.
2. Check denominator, radical, and logarithm domains.
3. Keep only candidates that satisfy both graphs.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Accepting transformed-equation roots without original check.
