The only thing that a square root symbol does is that it symbolises an operation (taking the square root) of whatever is under the sign.
9 is the square ROOT of 81. Calculating a square root is the inverse operation of squaring a number.

There is probably no square root button on the laptop keyboard. Look around in the software on the computer for an application called " Calculator ". That will have a button on it to perform the square root operation, plus buttons for a lot of other operations too.
The usual rules for "order of operation" apply. Don't forget that the square root of a negative number is an imaginary number. As an example, the square root of -9 is 3i (that is, the square root of +9, times the "imaginary unit").
Square root is the inverse operation of a square.
The inverse operation of taking the square root is to calculate the square.
Taking the square root is the opposite of squaring.

Squaring a number is the inverse of square rooting. The square root of 144 is 12, so 12 squared is 144.
Square roots? for example, 5 to the 2 is the square root of 5. 6 to the 3 is the cubed root of 6.
No. Negative numbers are real but their square roots are not.
The inverse operation is to take a square root.
You cannot perform any operation by giving any operator. The operation must be valid in the domain and range.For example, you often cannot perform the square rootoperation using the square root operator if your domain and range are integers. At the level of maths that I guess you are at (from this question), the square root of a negative number is not a operation that is defined.
Finding the square root of a number is performing the opposite operation of squaring the number. In order to square a number you must multiple the number by itself. 2 x 2 = 4 so the square root of 4 is 2.
