It is a perfect square.
Like every other number 1600 has only two square roots, plus and minus 40.
In some sense, yes. However, due to standard mathematical notation, the square root of 100 is 10. There are some things to note. First, when we use a square root sign (or any root sign) in math, it is assumed we mean the principal root. This is the root that is greater than or equal to 0. The principal root of 100 is 10, so when asked just for the square root of 100, it is generally assumed the answer is simply 10. To be more complete, when taking all second roots of 100 (all square roots), we get 10 and -10. The number -10 is a second root of 100, just not the principal root. Finally, when considering equations such as x2 = 100, we must take the positive and negative square roots of 100 (the principal root and inverse of the principal root) to find all the solutions. We get x = 10, -10.
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.
No. The square roots of perfect squares are rational.
It is a perfect square.
A number with a square root is still a number. So the answer is all of them.
-102 and 102 = 100 so 10 and -10
All integers are square roots. 3 is the square root of 9.

To round 2 decimal places for square roots all that needed is the knowledge to round just any number.
Yes. Because they have to be a rational number
I think you mean square root. The square root of a number is that number when multiplied by itself will give the original number. For example the original number is 4, then we know that 2 x 2 is 4, hence 2 is the square root of 4. We also know that -2 x -2 is also 4, hence 4 has two square roots, +2 and -2 Similarly 9 has two square roots, +3, and -3 Similarly 16 has two square roots, +4, and -4 Not all numbers have such whole numbers for their square roots. For example the square roots of 2 are nearly equal to +1.4142 and -1.4142. Similarly the square roots of 3 are nearly equal to +1.73205 and -1.73205

No. 19 is a prime number, and all prime numbers have irrational roots.
No. The square roots 8 are irrational, as are the square roots of most even numbers.
