Unclear.

Comment from student: Hi. Sorry, I forgot the last part of it. Let me type out the question and possible answers:
For which value of x does ((the square root of (x-5))+2=6? Possible answers: 69, 37, 21, 16 Thank you.

OK. If

sqrt%28x-5%29+%2B+2 = 6

then distracting 2 from both side

sqrt%28x-5%29 = 4,

and square both side

x - 5 = 16

gives the answer x = 21.
