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 10 019 is about 100.095.
Thus, the square root of 10 019 is not an integer, and therefore 10 019 is not a square number.
The square of a number (here 10 019) is the result of the product of this number (10 019) by itself (i.e., 10 019 × 10 019); the square of 10 019 is sometimes called "raising 10 019 to the power 2", or "10 019 squared".
The square of 10 019 is 100 380 361 because 10 019 × 10 019 = 10 0192 = 100 380 361.
As a consequence, 10 019 is the square root of 100 380 361.
