Zero is the only number that has only one square root.
The square root of zero is zero.
All other numbers have two square roots.
The square roots of 4 are 2 and -2. Two is referred to as the "principal" square root.
When you get to the grade that discusses imaginary/complex numbers, you'll learn that negative numbers also have square roots. The square roots of -4 are 2i and -2i. 2i is the principal square root.
a number can only be square if it has a square root.
289 is the only one.
[ 2 minus square root of 5 ] is the only one.
The square root of a positive number results in a positive number. For example, the square root of 25 is 5. * * * * * Not true! There are two real square roots for every positive number: one positive and one negative. -5 is as much a square root of 25 as +5 is. However, the positive root is the principal root and so is often presented as the only root.
When you double a number, the square root of the new one is sqrt(2) = 1.4142 times the square root of the original one.
If you mean square root when you say 'root'then... Yes, only the same number can be a square root and the factors of an even number must contain at least one even number So, if one of the roots is even then the other is the same number and is therefore even.
A number can have only one square root; for 9801, it's 99.
Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)
i is the symbol for an imaginary number, a complex number with the property i2=-1. The square root of a negative number is the square root times i. For example, the square root of -9 = 3i.
Every number has two square roots ... a positive one and a negative one. Example: +2 and -2 are both square roots of 4, because when you multiply either of them by itself, the answer is 4. The positive square root of a number is the square root that's not negative. The non-negative square root of a number is the positive one.
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.
No, a square number is one that has an integer for a square root and the square root of 36 is 5.83. The closest square number to 34 is 36 which is 6^2
The positive square root is.
A number to the one half power is the square root.
The square root
No. Since the square root of a number is whatever number times itself will equal the given number, there can be only one.
a is a real number since we use just letters to represent real numbers. if a > 0, then its square root is also a real number, so it has two square roots, one positive and one negative. Be careful when you use the radical sign, because it is looking only for the principal square root of a, which is the positive one. if a < 0, then its square root is an imaginary number.
Yes and no. It depends on your definition of square root. By the actual one, yes. All non-negative numbers have a square root. That square root might be irrational but it has a square root, nonetheless. 10 isn't a square number because there's no integer that can be squared to make ten but 10 definitely has a square root: 3.16227766....... If by square root you mean an integer square root, then no. If a number has an integer as its square root then you could square that integer to get the number, making it a square number.
No it is an Imaginary Number√-16 = 4ii is the square root of negative one
The square root of 1 is 1 which is a rational number
The square root of 100 is 10, and it is a rational number.
The square root of 1 is 1, so the answer is yes.
If this is supposed to be a riddle, it's not a very good one. The square root of the number whose square root is two is, obviously, two.
One definition of "root" is "the basic cause, source, or origin of something." The source of a perfect square is the number that was multiplied by itself to create it: the root of the square, the square root.
Only one answer is likely if you're looking for square roots, because the square root is the number times itself. For example, the square root of 64 is 8, because 8 x 8 = 64. There is no other way to get 64 by multiplying a number by itself.
