Well, butter my biscuit! The two square numbers that add up to 25 are 16 and 9. 16 is the square of 4, and 9 is the square of 3. So, 4 squared plus 3 squared equals 25. Math doesn't have to be as dull as dishwater!
9 + 16 = 25
The two square numbers that add up to 625 are 25 and 600. This is because 25 is the square of 5 (5^2 = 25) and 600 is the square of 24 (24^2 = 600). When you add 25 and 600 together, you get 625.
They are simply: 100+25 = 125
145
62.5 and 37.5
