comment How to calculate inverse of a matrix
Where did you find this matrix? There may not be a useful closed-form solution, in particular because when $m$ is a large number that matrix becomes fairly ill-conditioned to start with. I don't mean to imply that there is no closed form solution, but that formula is likely not going to be numerically stable. It may be better to try to invert that matrix numerically with preconditioned LU decomposition, or some other algorithm which can invert ill-conditioned matrices.

comment Finding a primitive element for a field extension
It seems to me like $\mathbb{Q}(2^{1/3}, 2^{1/4}) = \mathbb{Q}(2^{1/12})$, so $2^{1/12}$ is your primitive element.

comment Find a majorizing function
Oh, were you trying to use the dominated convergence theorem to switch the limit and integral? Is finding the value of that limit the original problem you started with?
