Let's denote the two square numbers as ( a^2 ) and ( b^2 ), where ( a ) and ( b ) are positive integers. The difference between these two square numbers can be expressed as ( b^2 - a^2 = 40 ). This can be factored as ( (b + a)(b - a) = 40 ). The factors of 40 are (1, 40), (2, 20), and (4, 10). By solving the system of equations, we find that the two square numbers are 49 and 9, as ( 7^2 - 3^2 = 49 - 9 = 40 ).

The sum of two numbers between 20-40 is 58. The difference is 12
2 Numbers are a and b. We have( a>b) a+b=40(1) and a-b=10(2) a=10+b( from 2. Subtracts both side by b) => 10+b+b=40 (from 1. Substitute a with 10+b) => 10+2b =40 => 2b =30 => b =15 =>a=10+15=25 => a=25 b=15.
Let's denote the two square numbers as x^2 and y^2. The difference between two square numbers can be expressed as (x^2 - y^2), which can be factored into (x + y)(x - y). Since the difference is 80, we have (x + y)(x - y) = 80. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. By testing out different combinations of these factors, we find that the pair of square numbers that make a difference of 80 is 82^2 and 2^2.
