But 141 is not a perfect square — check if 137, 138, etc., work. Try actual integers.
["Is 141 a Perfect Square? Exploring the Possibility and Testing Integers 137 to 144", "When we ask whether a number is a perfect square, we’re referring to an integer that is the square of another whole number. Perfect squares have neat, predictable properties, making them fundamental in math education, cryptography, and number theory. But what about 141 — is it perfect?
