The two square numbers that add up to 225 are 144+81 = 225
The two square numbers which add up to 13 are 9 (which is equal to 3 squared), and 4 (which is equal to 2 squared).
16,25,36 add to 77. They are the squares of consecutive numbers 4,5,6
x2 = 45take square root of both sidesx = positive and negative square root of 45x = + and - 3√(5)Improved Answer:-9 and 36 are square numbers and they add up to 45
