Explanation:

Step1: Define a constant polynomial

A constant polynomial is a single real number, which fits the form $a_nx^n+...+a_1x+a_0$ where all coefficients except $a_0$ are 0, and $a_0=3$.

Step2: Classify polynomial type

A polynomial with one term is a monomial; a constant is a monomial.

Step3: Find polynomial degree

The degree of a constant polynomial is 0, since $3 = 3x^0$.

Answer:

The given expression represents a polynomial. It is a constant monomial, and its degree is 0.
