Yes, square roots can be real numbers, but it depends on the value being square rooted.
For any non-negative number, the square root is defined as a real number. For example, the square root of 9 is 3, and the square root of 0 is 0. These results are part of the set of real numbers.
However, when you take the square root of a negative number, the result is not a real number. Instead, it falls into the category of imaginary numbers. For instance, the square root of -1 is represented as ‘i’, where ‘i’ is the imaginary unit.
In summary, square roots of non-negative numbers are real, while square roots of negative numbers are not.
