$- \sqrt{64} = - 8$ is an integer

#### Explanation:

As $64$ is a complete square, in fact it is ${8}^{2}$ i.e. square of a natural number / rational number, we have

$- \sqrt{64} = - 8$, and it is

an integer, also a rational number$\mathmr{and} m a y w e s a y$a real number.

But normally one describes it as the smallest set of number system to which it can be ascribed. Hence, we can say

$- \sqrt{64} = - 8$ is an integer
