yes they can if i know what you are asking
No, it is not even a real number. It is an imaginary number.
When it can be square rooted
No, it is not.
No, it is not.
- square rooted by 6
No because it can't be squared rooted evenly
infinity is not considered a number it is considered a theory therefore it can not be square rooted
The square of a real number is always a real number.
it depends on the number, for example the square root of nine is a natural number. it's 3. the square root of 3 is not a natural number. It is 1.73... and it goes on and on.
Of course, not only can it be a real number but it is a real number. When you take the square root times itself, the result is a number that is real.
I thought it was real... square of -x is the same as the square of +x
The square root of seven is a real number, but it is not a whole number.
