What a root square is?

Answer 1

The square root of a number is the factor which when multiplied by itself is equal to that number. i.e. 2 X 2 = 4, so 2 is the square root of 4.

A square root is a number that when listed as old school rows and columns in an abbacus, makes a perfect square (all sides are equal listing squares as multiplication in rows).

Example

2x2=4 and 4 is the square of 2 it was called a square because listing it as rows

OO

OO

we see 2 even sides on the (O's) on all sides, making a perfect square

lets try 3 the square root of 3 is 3x3=9 and we see below 3 objects on all sides making a perfect square (if we subtract the space in between the first amount) in the amount below listed as old school counting.

EDIT: The definition of a square root is a number which, when multiplied by itself, will give you your original number. The first contributor has demonstrated the numerical explanation.
The square root of a number is the number that must be multiplied by itself to get that number. if y is a number then the solution to the equation y=x^2 is the square root of y.

Answer 2

The square root of a number is 2 of the same numbers that can be multiplied together to get the original number.

Example:

The square root of 49 is 7 because 7 * 7 = 49.

The square root of 1521 is 39 because 39 * 39 = 1521.
