Answer 1

The correct description for the polynomial \( 5x^3 + 8 \) is **cubic binomial**.

Here's the reasoning:

- It is cubic because the highest degree term is \( 5x^3 \), which has a degree of 3.
- It is a binomial because it consists of two terms: \( 5x^3 \) and \( 8 \).

Therefore, the answer is **cubic binomial**.
