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 ANSWER is  =  = 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 4 seconds, having the formula typographically printed
in front of his (or her) eyes, such a person does not deserve to carry a honor title/degree of a Calculus student . . .
In Calculus, this question is the same as 1 + 2 = 3 in a kindergarten.
