What is the nonnegative square root of a number?
Definition of Square Root: The Square Root of a number 'X' is equal to 'A' when X=A*A By definition, the square root of a positive number has two answers, one negative and one positive, that have equal magnitudes. i.e. The square roots of 4 are 2 and -2. The Non-Negative Square Root is simply asking for the positive root.
Is the square root of one hundred less than or greater than or equal to twenty half's?
Equal, because the square root of 100 is 10, and 20 halves is also 10.
What is the square root of -363?
Such that the square root of 363 is equal to 19.05256 (rounded to five decimal places), the square root of -363 is euqal to 19.05256 i. The lower-case letter i represents the square root of minus one, an imaginary number.
What is the proof that a and b are positive numbers and a is less than b then the square root of a is less than the square root of b?
You cannot prove it because it is not necessarily true. A = 16 < B = 25 But one square root of A = +4 is not less than one square root of B = -5.
Does the square root of ab equal square root of a Times Square root of b?
Yes, that is correct. It is one of the basic properties of surds, and is used in many identities and some equations, to simplify and calulate and prove.
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 is one of 2 equal factors of a number or expression?
A Square Root is one of the two equal factors of a number.
One of the two equal factors of a number called?

How to do square root?
You find the same two numbers that make the number, then you use one of those numbers for your square root.
Why cant you get the square root of the sum of numbers?
You can. Just add the numbers together, and find their square root. One plus three is four; the square root of the sum is two.
If -6 is equal to the square root of 36 and that is equal to 6 then doesn't -6 equal 6?
No. Square root is not a proper function in the sense that, over the domain of negative and positive numbers, it is a one-to-many mapping. Strictly speaking the domain for square root is all non-negative or all non-positive numbers (or a subset of them). Consider the following mapping: Your mother is your parent, your father is your parent. But your mother is not your father.

Is the square root of -81 rational or irrational?
Since it is the square root of a negative number, it is actually imaginary, neither rational nor irrational. It is equal to 9i, or 9 times whatever the square root of negative one is.square root of -81 = square root of 81 times i = 9i
