The square root is the number which is times by itself, to get the square number.
81 -- 8+1 = 9 -- square root of 81 = 9
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.)
first of all the square root of any negative number is technically impossible, but in certain maths it can be accepted in terms of imaginary number, i. so to answer your question it is about 2.236067977i
81
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.

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.
