Why don't negative numbers have square roots?
They can, but they are called imaginary numbers. This is because a "square" of something is the number that, when multiplied by itself, will equal the first number. A negative multiplied by a negative equals a positive, and positives can't turn into negatives on their own, so there are no square roots of negative numbers.
Which two numbers have square roots equal to themselves?
The square root of zero is zero and the square root of one is one. No other real numbers have square roots equal to themselves. In other words, the solution set to x=x2 is {0,1}
What are two numbers that equal the square root of 3?
The square root of any non-square number is always irrational, so there is no way to use numbers (other than square roots, surds and squares) to show it precisely.
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.
Why are some numbers called square roots?
they are called square numbers because, the numbers that are being multiplied by itself(5x5=25)would equal its' sum OR answer. These numbers would be 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.
What does the square root of a number?
The square roots of a number are numbers and, as numbers, they are not capable of doing anything.
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

Numbers that are square roots that are whole numbers?
Every whole number

What is the square roots for -41.2?
There are none. Negative numbers don't have square roots. Well, they do, but they are known as imaginary numbers, and there is no way to determine them. A square root of a number is a number you can multiply by itself and get the original number. There is no number you can multiply by itself to get a negative number, but every positive number has two square roots of the same absolute value.
How many square roots do negative numbers have?
Negative numbers do not have "real number" square roots.However, they will have two roots (when using imaginary numbers) as do other numbers, where a root including i(square root of -1) is positive or negative.
When you have a number that has exactly two equal factors each factor is called?
If a number has equal factors, it is a perfect square and the equal factors would be square roots.
What does a non-zero rational number mean?
any number (including fractions, square roots and Pi) that are not 0 and are not square roots of negative numbers.
