Question

A number as a perfect square can never end with digits __________.

Answer 1

Answer:

A perfect square can never have digits 2,3,7 & 8 in the unit's place.

Step-by-step explanation:

As we know that all the perfect square number ends with  1,4,9,6,5,00

So, a number having 2,3,7 or 8 at the unit's place is never a perfect square.

Answer 2

All perfect squares end in 1, 4, 5, 6, 9 or 00 (i.e. Even number of zeros). Therefore, a number that ends in 2, 3, 7 or 8 is not a perfect square.
