How do you prove that an expression is not a perfect square?

How do you prove that an expression is not a perfect square?

  1. To prove that is not a perfect square, we need to find such that . Finding this (unique) for a given is a challenge.
  2. Since ends in , it must be the square of a number ending in . But the square of any such number is of the form , and so ends in .
  3. If , then must be of the form . Any integer can be written as , with .

Which number can never be a perfect square?

From the perfect squares found of all the numbers, it is obtained that 2, 3, 7, and 8 are the number that can never exist on the unit place of a Perfect Square. The other numbers like 1, 4, 5, 6, 9 can come at the unit place of the perfect square.

Is 9 + 2n – 8 a perfect square?

Therefore, 9 + 2n − 8 has to be a perfect square. Clearly, 9 + 16 = 25 is a perfect square. Hint: (2a + 2b)2 = 22a + 22b + 2a + b + 1. If 0 ≤ n ≤ 7, then there are no solutions.

Can two perfect squares have a difference of 1?
