Mixed power relations-4
Another associated property of the relation a2 + b2 + c2 = 2 d is d+ xy = (x+y)2 = c2
12 + 122 + 132 = 2 x 157 ; 157 + 1x12 = 169 = 132
22 + 112 + 132 = 2 x 147 ; 147 + 2x11 = 169 = 132
32 + 102 + 132 = 2 x 139 ; 139 + 3 x 10 = 169 = 132
42 + 92 + 132 = 2 x 133 ; 133 + 4x9 = 169 = 132
52 + 82 + 132 = 2 x129 ; 129 + 5 x8 = 169 = 132
62 + 72 + 132 = 2 x127 ; 127 + 6x7 = 169 = 132
