Answer 2

Answer :

★ If a number ends with 2,3,7 and 8 and if it has a odd number of zeroes, then it's not a perfect square.

Let's come to the question -

a) 153

• 153 ends with 3, So, it's not a perfect square.

b) 257

• 257 ends with 7, So, it's not a perfect square.

c) 408

• 408 ends with 8, So, it's not a perfect square.

d) 441

Since, 441 doesn't ends with 2,3,7 and 8. So, it's a perfect square.
