Question

Is 18 a polynomial? Explain your reasoning

Answer 1

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

Answer 2

yes, 18 is a polynomial

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.
