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.
