Answer 2

Answer: The answer is (D) cubic monomial.

Step-by-step explanation: The given polynomial is
`5x^3.`

We are to select the correct description of the above polynomial from the given options.

Since there is only one term in the polynomial, so it is a monomial.

Also, the power of the unknown variable is 3, so the degree of the polynomial is 3 and so it is a cubic polynomial.

Therefore, the given polynomial is a cubic monomial.

Thus, (D) is the correct option.
