Yes, they are! For instance, let's say you have √2. (√ is the symbol for square root incase you were unsure - don't mean to offend you.) Now, if you were to square the square root of two, (√2)², it would equal 2! Also, you can "undo" powers with square roots, and vice versa! For example, √9 = 3 and 3² = 9! Another one is, √4 = 2 and 2² = 4. Hope this helps!
A square root is a number raised to the exponent (power) 1/2.
The square root is the number which is times by itself, to get the 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.)
The square root of a negative number is not real.
If a number is squared you get a new number called the square of the given number. When the square root of the new number is taken you get back the original given 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 length of a side of a square is the square root of the area of the square.

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.
