    Alternative? use sequence for Z(n )= X^n + 1/X^n here Z(1)=5^(1/2). (Z(0)=2) Recursion Z(n+1)=Z(n)Z(1)-Z(n-1)
    (Also doubling formula Z(2n) = Z(n)^2). Here need to get Z(3) and then doubling formula [ Z(1), Z(2), Z(3) ]=[ 5^(1/2), 3, 2*5^(1/2)].
    Now Z(6)=Z(3)^2-2 =18. Z(12)= Z(6)^2-2 =322. So we have, (X^12+ 1/X^12) = 322. => X^12= 161+72*5^(1/2)

    Greetings. Thanks always for sharing and for pointing out the pitfalls that would have been encountered if one were to have resorted to employ the usage of Pascal's triangle. That was absolutely what came to mind when the expression was reduced to the 6th power. It was indeed a sweet little problem. Thanks again. Blessings.

    Much too long!! Be a = (1+sqrt(5))/2
    a^3 = (1+3.sqrt(5) +15+5.sqrt(5))/8 = 2+sqrt(5)
    So a^6 = (2+sqrt(5))^2 = 4+4.sqrt(5)+5 = 9+4.sqrt(5)
    And so a^12 = (9+4.sqrt(5))^2 = 81+72.sqrt(5)+80
    Finally a^12 = 161+72.sqrt(5). That's all!

    You confused yourself along the way. I wonder what that will do to your students. Besides, you have not shown that your final answer is correct.
