Question

Can we say whether the following number are perfect square. How do you know. reasons (1) 23453​

Answer 1

Answer:

No

Step-by-step explanation:

∴ 23453 is not a perfect square. Since, the ending digit is 8 (which is not one of 0, 1, 4, 5, 6 or 9). ∴ 7928 is not a perfect square. Since, the ending digit is 2 (which is not one of 0, 1, 4, 5, 6 or 9).

Answer 2

Answer:

No, 23453 is not a perfect square.

We can say that easily, because no perfect squares end in number 3.

Not only 3, but 2, 7, and 8 also.

If a number ends in 2, 3, 7, or 8, then it is definitely not a perfect square.
