Question

Is 193 a perfect square?

Answer 1

No.

Explanation:

The fact that `sqrt193` is an irrational number proves that it is not a perfect square, as `sqrt193=13.89244` without ever having an end.

Furthermore, the surrounding perfect squares are `169` and `196`, which are `13^2` and `14^2` respectively. Since `169<193<196`, `193` cannot be a perfect square.
