What is a number that has integers at all its square roots?
It is a perfect square.
What are all the square roots of 1600?
Like every other number 1600 has only two square roots, plus and minus 40.
Is -10 a square root of 100?
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.
What kind of number system is a square root?
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.
Are all square roots are irrational numbers?
No. The square roots of perfect squares are rational.
What is a number that has integers at all its square roots?
It is a perfect square.
What are the numbers with square roots that are numbers?
A number with a square root is still a number. So the answer is all of them.
All the square roots of 100?
-102 and 102 = 100 so 10 and -10
Is 3 a square root number?
All integers are square roots. 3 is the square root of 9.
What are all the square roots of 1600?
Like every other number 1600 has only two square roots, plus and minus 40.

How do you round two decimal places for square roots?
To round 2 decimal places for square roots all that needed is the knowledge to round just any number.
Are all imperfect square roots repeating decimals?
Yes. Because they have to be a rational number
What is square root-?
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

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