A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 11 006 is about 104.909.
Thus, the square root of 11 006 is not an integer, and therefore 11 006 is not a square number.
The square of a number (here 11 006) is the result of the product of this number (11 006) by itself (i.e., 11 006 × 11 006); the square of 11 006 is sometimes called "raising 11 006 to the power 2", or "11 006 squared".
The square of 11 006 is 121 132 036 because 11 006 × 11 006 = 11 0062 = 121 132 036.
As a consequence, 11 006 is the square root of 121 132 036.
