Yes and it is 2
Yes, the whole idea of taking the "square root" of a number is, for example for the square root of 2, to find the number that, when squared, gives you 2. if you try to do both, they cancel each other out.
The square root of 2 is an irrational number because it can't be expressed as a fraction
If the square root is a whole number, then the square of the square root, the original number, is also a whole number; all whole numbers can be expressed as themselves over 1, and so are rational numbers. The answer is thus any square number, ie the square of the natural numbers: 1 (1²), 4 (2²), 9 (3²), 16 (4²), etc.
Some square roots of whole numbers are integers, some of them are irrational numbers. The square root of four for instance is a rational number, 2. The square root of two however is an irrational number, approximately 1.414211356.
Yes. The square of a whole number is always a whole number. For example, 3 squared is 9, so the square root of 9 is 3. What you never have, is the square root of a whole number being a fraction that is not a whole number. The square root of a whole number is either a whole number or an irrational number. For example, the square root of 2 is irrational, because there are no 2 whole numbers a and b such that a/b squared is 2. This is not terribly difficult to prove, but I have already said too much; I have answered your question.

No, it may be not even a rational number. Square root of 2 is 1,414213562... for example.

It is rational. The root of a perfect square, such as 4, is rational; the root of any positive integer that is not a perfect square is an irrational number.

yes...it is 1.41421356try it on a calculatorEvery positive number has a square root. In fact,every positive number has two of them.There is a square root of any number, but the square root of most numbers is not a whole round number. The square root of 2 is 1.41421

The square root of 3 falls between 1 and 2. (It is closer to 2 though)
Well the square root of 6 is 2.449... so when rounded to the nearest whole number it would be 2, but that would be a very inaccurate answer you should leave it in the square root form or 2.5 if anything.
