उत्तर
The numbers whose last digit is odd can never be the square of even numbers use prime factorisation method and make pairs of equal factors.
324 = 2 x 2 x 3 x 3 x 3 x 3
= (2 x 2) x (3 x 3) x (3 x 3)
There are no factors that are not paired. Hence, 324 is a perfect square. The square of an even number is always even. Hence, 324 is the square of an even number.
