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.
3 is the square root of 9. 9 is a square number. 9 is the square root of 81. 81 is a square number.
No - a natural number is a whole number. Therefore, the square root of 49 is a natural number, but the square root of 50 is not.
The square root of 51 is an irrational number and it is about 7.14128429
A perfect square root is where the square root of a number equals another whole number. For example, the square root of 144 is 12. 12 is a whole number thus 144 is a perfect square root.
The opposite of a square root is the square of a number. In mathematical terms, if the square root of a number x is denoted as √x, then the opposite of the square root (√x) is x itself. This is because squaring a number undoes taking the square root of that number.
The square root is the number which is times by itself, to get the square number.
Sometimes the square root of a positive number can be irrational, as in the square root of 2 (which is a non-perfect square number), but sometimes it is a rational number, as in the square root of 25 (which is a perfect square number).
3 is the square root of 9. 9 is a square number. 9 is the square root of 81. 81 is a square number.
the square root of a number is the number that is multiplied by itself to get that number, for example the square root of 9 is 3
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.)
It's not a square if it has no root. If a number is a square then, by definition, it MUST have a square root. If it did not it would not be a square.
The number 3 is the square root of the number 9 !
Oh, dude, the square root of 25 is 5, which is a whole number and can be expressed as a fraction 5/1. So, yes, it is a rational number because it can be written as a ratio of two integers. But hey, who really cares about all that math stuff anyway, right?
No - a natural number is a whole number. Therefore, the square root of 49 is a natural number, but the square root of 50 is not.
The square root of 51 is an irrational number and it is about 7.14128429
No it is not.
The square root of 20 is: ± 4.472136The square root of 20 is ± 4.472136 (to 7 sf).A square root of a number is the number that when multiplied by itself equals the given number.
