I'm restoring the "radicals" tag. See my comment.

comment Are logarithms radicals?
@RobArthan : What do you mean by "radicals in the accepted sense of the term"? I would take that to mean things like $\sqrt 2$ and $\sqrt[3] 2$, etc. It appears to me that that is what the question is about. ${}\qquad{}$

comment What operations can I do to simplify calculations of determinant?
@alkabary : In your attempted edit you had \space|\space. I changed that to \mid. I think that's better than inserting spaces manually because the spacing conventions that apply to it are different in different contexts and the software knows how the conventions vary with the context.

comment Why should statistics be considered mathematics?
@talmudist : You could also ask whether probability is about chance or about uncertainty. If someone says there's 50% chance that there was life on Mars a billion years ago, that's about uncertainty, not about chance. And the question of chance-versus-uncertainty is not a mathematical question. ${}\qquad{}$
