Question

What is the set of numbers to which `-sqrt64` belong?

Answer 1

`-sqrt64=-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

`-sqrt64=-8`, and it is

an integer, also a rational number`and may we say`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

`-sqrt64=-8` is an integer
