To solve the given mathematical problem, we need to find the square root of 25. The square root of a number [tex]\( x \)[/tex] is a number [tex]\( y \)[/tex] such that [tex]\( y^2 = x \)[/tex].
Here, we need to find a number [tex]\( y \)[/tex] such that:
[tex]\[ y^2 = 25 \][/tex]
We recognize that if we square the number 5, we get:
[tex]\[ 5^2 = 25 \][/tex]
Thus,
[tex]\[ \sqrt{25} = 5 \][/tex]
Among the given choices:
- A. 4
- C. 5
- n ∞
The correct answer is:
[tex]\[ \boxed{5} \][/tex]
