Question

if a number ends with the digits 2,3,7 and 8 then the number is always a non perfect square (true /false) ​

Answer 1

Answer:

If we see the above results carefully, we can conclude that numbers ending with 0, 1, 4, 5, 6, or 9 at units place are perfect squares None of these end with 2, 3, 7 or 8, So numbers that end with 2, 3, 7, 8 are not perfect squares. Thus, numbers like 122, 457, 183, 928 are not perfect squares.
