Answer:

  B.  27

Step-by-step explanation:

Try the answers and see what works. It helps if the equation is written properly.

  √(27 -2) = 27 -22

  √25 = 5 . . . . . true

None of the other choices gives a rational value for √(x -2).

_____

<em>Comment on the question</em>

As written, the answer is x=25; not on your list. This is how we can tell the question is not written properly.

  √25 -2 = 25 -22

  5 -2 = 3 . . . . . true
