The square root of a number
y is another number
x such that
x^2 = y.


So, the square root of 25 is another number x such that
x^2 = x \cdot x = 25


You can clearly see that the integer number 5 satisfies this request, so the square root of 25 belong to the integer numbers set, denoted as
\mathbb{Z}
