.
Unclear.


---------------------------
<U>Comment from student</U>: 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(x-5) + 2}}} = {{{6}}}


then distracting 2 from both side


{{{sqrt(x-5)}}} = 4,


and square both side


x - 5 = 16


gives the answer x = 21.
