Perfect square of 401

apparently In what I believe, 401 is not a perfect square mate!

Step-by-step explanation:

401 is an odd number, because it is not evenly divisible by 2.

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 401 is about 20.025.

Thus, the square root of 401 is not an integer, and therefore 401 is not a square number.
