Exercise 21 Page 10

A polynomial is a monomial or the sum of monomials. The degree of a polynomial is the degree of the monomial with the greatest degree.

Is the Expression a Polynomial? Yes.
Degree of the Polynomial: 0
Type of Polynomial: monomial

Practice makes perfect
To determine whether the given expression is a polynomial, recall that a polynomial is a monomial or the sum of monomials.

A monomial is either a number, a variable, or an expression that is the product of one or more variables with non-negative integer exponents.

Consider the given expression. 21 This expression is a polynomial because it is a number. The degree of a polynomial is the degree of the monomial with the greatest degree. For our monomial, the degree is 0.
