Every positive real number has two square roots: one negative and one positive. As a result, the square root mapping is one-to-many and so is not a mathematical function. One way to make it a function is to restrict the range to non-negative real numbers. These are the non-negative square roots.

Yes.
The nonnegative square root of a number?
The unique nonnegative square root of a nonnegative real number. For example, the principal square root of 9 is 3, although both -3 and 3 are square roots of 9.

What is the symbol used to represent the nonnegative square roots of a number?
There are no explicit symbols. The non-negative square toot is called the principal square root.
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.
What is the symbol used to indicate a nonnegative square root?
it looks like a check mark. it is called the radical. it looks like this --> √
Which is equal to square root of 48y2 Assume y is nonnegative?
sqrt(48y2) = sqrt(3*16y2) = sqrt(3)*4y = 6.928y (approx)
The symbol used to indicate a nonnegative square root?
The is only one unambiguous way and that is to use the modulus, thus: |√x| Some people do use +√x but, of course, this could be mean add the square root -whatever its sign.
