"squaring" any number means to multiply it times itself. Using your examples:
5 x 5 = 25 (You must have already memorized what 5 x 5 equals).
4 x 4 = 16 (Also must have already been memorized)
The prime numbers with square roots between 4 and 5 are 5 and 7.
The square numbers between 1 and 30 are 1, 4, 9, 16, and 25. These correspond to the squares of the integers 1 through 5 (1², 2², 3², 4², and 5²). Thus, the square numbers in this range are 1, 2, 3, 4, 5.
25= 5*5 = (3*3)+(4*4)
The two square numbers that, when subtracted, equal 5 are 9 and 4. Specifically, (3^2 = 9) and (2^2 = 4), and when you subtract them, (9 - 4 = 5).
If you subtract one square number from another and the result is 5, the two square numbers are 9 and 4. This is because (9 - 4 = 5), where (9) is (3^2) and (4) is (2^2). Thus, the two numbers are 3 and 2.

25= 5*5 = (3*3)+(4*4)
The first 5 square numbers are 1, 4, 9, 16, and 25.
The two square numbers that, when subtracted, equal 5 are 9 and 4. Specifically, (3^2 = 9) and (2^2 = 4), and when you subtract them, (9 - 4 = 5).
4 and 9
If you subtract one square number from another and the result is 5, the two square numbers are 9 and 4. This is because (9 - 4 = 5), where (9) is (3^2) and (4) is (2^2). Thus, the two numbers are 3 and 2.
4 and 9
-5 and -4 or 4 and 5
The two square numbers are 9 and 4. When you subtract 4 (which is (2^2)) from 9 (which is (3^2)), the result is 5: (9 - 4 = 5). Thus, the numbers are 3 and 2.
9, the square of 3, and 4, the square of 2
There are 5 square numbers under 30: 1, 4, 9, 16, and 25.
