Is 23abc a polynomial? I want to say it is because all it is is multiplication but, I'm not positive. If it is, it would be a constant monomial thought right?

If you look up the definition of a polynomial, you will find the answer.

The definition of a polynomial is:
"In mathematics, a polynomial is a finite length expression constructed from variables (also known as indeterminates) and constants, by using the operations of addition, subtraction, multiplication, and constant non-negative whole number exponents."

To determine whether 23abc is a polynomial, we need to understand the definition of a polynomial.

A polynomial is an algebraic expression consisting of variables, constants, and powers of variables, combined using addition, subtraction, and multiplication operations. The variables can have non-negative integer exponents.

In the expression 23abc, we have three variables (a, b, and c) multiplied with each other and with the constant 23. Since there are no addition or subtraction operations involved, we only need to assess whether this expression meets the criteria of a polynomial.

Therefore, 23abc is indeed a polynomial since it is a product of variables and a constant. Specifically, it is a monomial, which is a polynomial with only one term. In this case, the term is 23abc, and since it contains no addition or subtraction, it is considered a constant monomial.

In summary, your understanding is correct. 23abc is indeed a polynomial, specifically a constant monomial.
