X + 1/X=2 cos theeta... then the value of Xpower6+1/Xpower6=??

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.
