25 (32 + 42 = 52)
25 is the sum of 9 and 16. (52 = 32 + 42)
25= 5*5 = (3*3)+(4*4)
12+22+32+42+52+62 = 1+4+9+16+25+36= 91
25 = 9 + 16 There are many more sets like these. This one has the smallest numbers.

25 is a square number, and the sum of 9 and 16 is 25. 9 and 16 are also square numbers.
25 is the sum of 9 and 16. (52 = 32 + 42)
25= 5*5 = (3*3)+(4*4)
94 - 1^2 + 2^2 ... 6^2.
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
10^2 = 6^2 + 8^2 ie 100 = 36 + 64
12+22+32+42+52+62 = 1+4+9+16+25+36= 91
