释义

Diophantine Equation--8th Powers

The 2-1 equation

(1)

is a special case of Fermat's Last Theorem with

, and so has no solution. No 2-2 solutions are known.

No 3-1, 3-2, or 3-3 solutions are known.

No 4-1, 4-2, 4-3, or 4-4 solutions are known.

No 5-1, 5-2, 5-3, or 5-4 solutions are known, but Letac (1942) found a solution to the 5-5 equation. The smallest5-5 solution is

(2)

(Lander et al. 1967).

No 6-1, 6-2, 6-3, or 6-4 solutions are known. Moessner and Gloden (1944) found solutions to the 6-6 equation. Thesmallest 6-6 solution is

(3)

(Lander et al. 1967).

No 7-1, 7-2, or 7-3 solutions are known. The smallest 7-4 solution is

(4)

(Lander et al. 1967). Moessner and Gloden (1944) found solutions to the 7-6 equation. Parametric solutions to the 7-7 equationwere given by Moessner (1947) and Gloden (1948). The smallest 7-7 solution is

(5)

(Lander et al. 1967).

No 8-1 or 8-2 solutions are known. The smallest 8-3 solution is

(6)

(Lander et al. 1967).Sastry (1934) used the smallest 17-1 solution to give a parametric 8-8 solution. The smallest 8-8 solution is


	(7)

(Lander et al. 1967).

No solutions to the 9-1 equation are known. The smallest 9-2 solution is

(8)

(Lander et al. 1967).Letac (1942) found solutions to the 9-9 equation.

No solutions to the 10-1 equation are known.

The smallest 11-1 solution is

(9)

(Lander et al. 1967).

The smallest 12-1 solution is

(10)

(Lander et al. 1967).

The general identity

(11)

gives a solution to the 17-1 equation (Lander et al. 1967).
