  1. 16 can be broken down into 4•4=42, so 16 is a perfect square

  3. 4, 9, 16, 25, 36, 49, 64, 81, and 100 are perfect squares

    1. 4 is an integer, and 42 is 4•4=16

    1. 4 • 4 = 42
    2. 16 is a perfect square in part because 4 is an integer
    1. After all, we can just count up from one, and keep squaring integers to get more perfect squares
