The square numbers between 30 and 50 are 36 (6^2) and 49 (7^2). A square number is a number that is the result of multiplying an integer by itself. In this case, 6 multiplied by 6 equals 36 and 7 multiplied by 7 equals 49.
The first 4 square numbers are 1^2, 2^2, 3^2, and 4^2, which are 1, 4, 9, and 16, respectively. To find the sum of these numbers, you simply add them together: 1 + 4 + 9 + 16 = 30. Therefore, the sum of the first 4 square numbers is 30.
