Question 1178315
.


My dear visitor,


your post is written INCORRECTLY.



Such problems MUST contain the part  " x ---> to something",

which ABSENTS in your post.



Therefore, your post is UNREADABLE.



//////////////



After spending significant time for guessing,  I finally  DECIPHERED  what you were going to ask:



            Find    lim  (x-->3)  {sqrt(x^2+7) + 5}.



The &nbsp;<U>ANSWER</U> &nbsp;is  &nbsp;&nbsp;{{{sqrt(3^2+7) + 5}}} = {{{sqrt(16) + 5}}} = 4 + 5 = 9.




If you see the formula, typographically printed in front of your eyes, 

then the time to solve it and to answer is about 4 seconds.



So, I really do not understand the reason why you posted it to the forum . . . . 




If the student can not answer this question in &nbsp;4 &nbsp;seconds, &nbsp;having the formula typographically printed 


in front of his &nbsp;(or her) &nbsp;eyes, &nbsp;such a person does not deserve to carry a honor title/degree of a &nbsp;Calculus student . . . 



In &nbsp;Calculus, &nbsp;this question is the same as &nbsp;&nbsp;1 + 2 = 3 &nbsp;&nbsp;in a kindergarten.
