(9 – 8)^c + (7 – 6)^5 + (3 – 1)^2 = 6, c=7

(9 – 8)^c + (6 – 3)^4 + (2 – 7)^1 = 77, c=6

(2 – 4)^c + (6 – 3)^1 + (5 – 7)^8 = 323, c=6

–all

(8 – 4)^c + (6 – 7)^3 + (9 – 1)^5 = 36863, c=6

(4 – 8)^c + (6 – 7)^3 + (9 – 1)^5 = 36863, c=6

(2 – 3)^c + (9 – 1)^5 + (8 – 4)^6 = 36863, c=9

(2 – 3)^c + (9 – 1)^5 + (4 – 8)^6 = 36863, c=9
