Yes and it is 2
The square root of 15 being 3.87 the closest whole number would be 4
4
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.
No, it is in between 3 and 4
Yes because it is 4
The square root of 16 is 4 which is a whole number.
The square root of 15 being 3.87 the closest whole number would be 4
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, because the square root of 16 is 4 and as a whole number it is an integer
No, it is in between 3 and 4
Yes because it is 4
Approximately 4.
No. to be a perfect square, you have to be able to square root it and get a whole number (NOT a decimal) the square root of 3 is 1.732. (1.7322 = 3) a perfect square is a number like 4 the square root of four is 2 (22 = 4)
* Its square root is a whole #. Example: 16 is a perfect square. Its square root is 4. 17 is not a perfect square. Its square root is around 4.123105626
Yes, the square root of 48 is an irrational number. This is because 48 can be simplified to (4 \times 12), and since the square root of 4 is a whole number (2), we can express (\sqrt{48}) as (2\sqrt{12}). The square root of 12, however, is not a perfect square and cannot be simplified to a whole number, making (\sqrt{48}) irrational.
