The attribute that they have one square root which belongs to the set of natural numbers.
Yes, the square root of negative 121 is undefined in the set of real numbers. However, in the set of complex numbers, the square root of negative 121 is equal to 11i, where i is the imaginary unit.
That's the same as the square root of positive 340, times i. Many calculators can't calculate the square root of negative numbers, since they are not set up to calculate with complex numbers, but you can simply calculate the square root of the equivalent positive number, then add "i" to the result.
It is an irrational number.
A square root is not a number system. Square roots of non-negative numbers may be rational or irrational, but they all belong to the set of real numbers. The square roots of negative numbers do not. To include them, the number system needs to be extended to the complex numbers.

Root 6 is an irrational [real] number.
No, it is not irrational because it is a square root of a negative number - which falls into the set of Complex numbers. Irrational numbers can not have an imaginary component.
There is just one set of square numbers; it is the set of all numbers which are squares of whole numbers:- i.e 1, 4, 9, 16, 25, 36, 49, ... and so on up to infinity in other words, it's the set of all numbers whose square root is a whole number.

It belongs to many many subsets including: {sqrt(13)}, The set of square roots of integers The set of square roots of primes The set of square roots of numbers between 12 and 27 {3, -9, sqrt(13)} The set of irrational numbers The set of real numbers
