    Perfect Squares

    • Definition: A perfect square is an integer that can be expressed as the square of another integer.

    List of Perfect Squares

    1. 1² = 1
    2. 2² = 4
    3. 3² = 9
    4. 4² = 16
    5. 5² = 25
    6. 6² = 36
    7. 7² = 49
    8. 8² = 64
    9. 9² = 81
    10. 10² = 100
    11. 11² = 121
    12. 12² = 144
    13. 13² = 169
    14. 14² = 196

    Properties of Perfect Squares

    • Always non-negative.
    • The square root of a perfect square is an integer.
    • The last digit of a perfect square can only be 0, 1, 4, 5, 6, or 9.
    • The difference between consecutive perfect squares increases linearly (e.g., 1, 3, 5, 7,...).

    Applications of Perfect Squares

    • Used in geometry to calculate areas of squares.
    • Important in algebra for factoring and solving quadratic equations.

    Definition of Perfect Squares

    • A perfect square is an integer that can be written as the square of an integer.

    List of Perfect Squares

    • 1 is a perfect square (1² = 1).
    • 2 produces 4 (2² = 4).
    • 3 results in 9 (3² = 9).
    • 4 gives 16 (4² = 16).
