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 11 002 is about 104.890.
Thus, the square root of 11 002 is not an integer, and therefore 11 002 is not a square number.
The square of a number (here 11 002) is the result of the product of this number (11 002) by itself (i.e., 11 002 × 11 002); the square of 11 002 is sometimes called "raising 11 002 to the power 2", or "11 002 squared".
The square of 11 002 is 121 044 004 because 11 002 × 11 002 = 11 0022 = 121 044 004.
As a consequence, 11 002 is the square root of 121 044 004.
