Answer 2

Heya!! ⭐⭐

No, 1280 is not a perfect square..

Check :- We split the number and add each of its digits. we get..

1 + 2 + 8 +0 = 11

Let us add it's digits. we get..

1 + 1 = 2

Hence, we get the digit root as 2. And we know that a number ending with 1, 4, 7& 9 are perfect squares..

So we can say that 1280 is not a perfect square......

Hope it helps :-)
