Answer
polynomial of degree 3.
Work Step by Step
Polynomials consist of one or more monomials and have the form:
$$a_nx^n+a_{n-1}x^{n-1}+...+ a_1x+a+0$$
where $x$ is the variable, $a_n$ is the leading coefficient, and $n$ is a non-negative integer called the degree.
We are given the polynomial
$$2y^3+\sqrt 2$$
Comparing with the polynomial general form, we see that this is a polynomial with degree $3$.
