A polynomial of degree n is an expression of the form:
where a, b, c, ...d, e, f are Real numbers, and any of them can be = 0, except a.
and the degrees, n, n-1, .... are all non-negative integers: {0, 1, 2, 3 ...}
Among our choices,
the first one,
,
does not fit the polynomial definition, so the expression is not a polynomial.
the second one, is a fifth degree polynomial
the third one,
is a fourth degree polynomial.
the fourth one,
is not a polynomial
