"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.
25= 5*5 = (3*3)+(4*4)
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.
9, the square of 3, and 4, the square of 2
They are 4 and 5
