Question

Writing Give an expression that is a monomial and tell why it is an example of a monomial. Then give an expression that is not a monomial and tell why it is not an example of a monomial.

Short answer

Example of a monomial is = 6x²y. It is a monomial because it has only one term.

Example of an expression that is not monomial is: 7x + 5y. It has two terms, so it is not a monomial.

Step-by-step solution

Step-1 – To determine

We have to give an expression for a monomial and a polynomial.

Step-2 – Definition

Monomial means an expression with only one term. Example: 5ab

Polynomial means an expression with many terms. Example: 2a³ + 3ab² + 5b².

Step-3 – Reason

Example of a monomial is = 6x²y. It is a monomial because it has only one term.

Example of an expression that is not monomial is: 7x + 5y. It has two terms, so it is not a monomial.
