I am weak in this topic but I am certain that the following is has a solution in integers A,B,C,D.
Find A,B,C and D as integers such that
[tex] (3*2^{.75} + 7*2^{.50} + 7*2^{.25} + 7)*(A*2^{.75} + B*2^{.50} + C*2^{.25} + D) = 2047*(2^{.75} + 2^{.50} +2^{.25} + 1) [/tex].
I deduced this by studying the recursive sequence [tex]S^{n} = 3*S_{n-1} - 2*S_{n-2}[/tex] That is {1,3,7,15,31, ...}
Thanks for any pointers.
