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.

Square root 2 times square root 3 times square root 8?
square root 2 times square root 3 times square root 8
What is the square root of 4x?
We use the property of square roots that says the square root of (ab)=square root (a) multiplied by square root of b So square root (4x)=square root (4) mutiplies by square root of x =2(square root (x)) 2sqrt(x)
What numbers are always irrational?
the square root of 3, the square root of 5, the square root of 6, the square root of 7, the square root of 8 etc
What is the square root of 75 divided by the square root of 3?
Square root (75) / square root (3) = 5
What do you call the nonnegative square root?
The principal square root.
Is a nonnegative square root called a principal square root?
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 equal to two equals factors of my nonnegative number?
The square root.
What is a radical sign?
The symbol used to indicate a nonnegative square root.
What is one of two equal factors of a nonnegative number called?

What is the symbol used to represent the nonnegative square root of a number?
The radical symbol ( √ ) followed by a line above what's in the radical, designates positive square root.
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.
