#### Answer

Standar form: $5x^3$
Degree = 3
Number of terms = 1
This polynomial is a cubic monomial.

#### Work Step by Step

RECALL:
A polynomial is written in standard form if its terms are written in descending degree.
The given expression has two terms with the same degree (they are like terms) so combine them to have:
$(6-1)(x^3)
\\=5x^3$.
This polynomial has degree 3 and has one terms. It is a cubic monomial.
