Is this what you mean?:
x+\frac{1}{x}=2cos{\theta}, then
x^{6}+\frac{1}{x^{6}}=?
That is what you have written.
Unless you mean:
If \frac{x+1}{x}=2cos{\theta}, then
\frac{x^{6}+1}{x^{6}}=?
Just making sure.
By the way, why not use ^ (SHIFT 6) for a power instead of typing out 'power'?

And make use of brackets too to avoid confusion.
