The value of the limit expression 
is 9, and it means that the function approaches 9, as x approaches 3.
<h3>How to evaluate the limit?</h3>
The limit expression is given as:
This means that we determine the value of the function as x approaches 3.
So, we have:
Limit = √(3^2 + 7) + 5
Evaluate the square
Limit = √(9 + 7) + 5
Evaluate the sum
Limit = √16 + 5
Evaluate the square root
Limit = 4 + 5
Evaluate the sum
Limit = 9
Hence, the value of the limit is 9
