Question

Is 18 a polynomial? Explain your reasoning

Answer 1

Answer:

yes, 18 is a polynomial

Step-by-step explanation:

We have to show whether 18 is a polynomial or not

Polynomial is an expression involving variables and constants such that variables having non negative integer power.

Example $2x^4, 3y^3$ etc,

Thus, yes 18 is a polynomial

as 18 can be written as $18x^0$ where $x^0=1$ and 0 is non negative integer,

Thus, yes 18 is a polynomial as it can be written as $18x^0$  having non negative integer power 0.

Answer 2

Yes, 18 is a monomial because it is an expression with one term
