A, D, E, F are. Others are not. B has x in radical, and C has variables in the denominator.

Even if the variables are in the radicals, you can still express them as: \[x^{n} \] similarly, \[\sqrt{x} = x ^{\frac{ 1 }{ 2 }}\]

That's not a polynomial, though. In a ploynomial, variables can only have nonnegative exponents.
