x^10+1/x^10=3
x^20+1/x^20=7
x^80+1/x^80=2207
x^130+1/x^130=271443

Let x^10=a so k=a^13+1/a^13
a^8+1/a^8=2207 & a^5+1a^5= 123 hence
?= k= (2207×123)-18=271443 soln.

(x ➖ 1) (x ➖ 1x+1) x^1(x^3 ➖ k) (k ➖ 3x+1).

χ^10+(1/χ^10)=3 ; χ^130+(1/χ^130)=Κ
Αν χ^10=α τοτε (χ^10)^13=α^13
Κ=α^13+(1/α^13)
α^2+1/α^2=7 ; α^3+1/α^3=18
α^4+1/α^4=47 ; α^6+ 1/α^6=322
α^8+1/α^8=2207 ; α^10+1/α^10=15127
α^13+1/α^13=272286-843=271443
Κ=271443.
