A polynomial which contains only one non-zero single term is called a monomial. A monomial consists either one variable or a constant or products of more than one variable with a coefficient along with the exponents as a whole numbers.

Note: A monomial cannot have a variable in the denominator. The variable in the denominator is considered as second term.

The different parts of the monomial expression are given as follows:

Coefficient:The number which is multiplied by the variable in the expression.

Variable: The alphabets present in the monomial expression are called as variables

Literal part: All the other parts except the coefficient, are called the literal part of the expression.

Degree:The sum of the powers of the variables in the expression is the degree of the expression.

Example:$5a^2{b}^3$is a monomial expression.

Here,see that the coefficient is 5.

Variables in the given expression are a andb.

The literal part of the expression is $a^2{b}^3$.

From the definition, a monomial expression must contain only one non-zero term.

The expression$2c+2$contains plus sign andtwo non-zero terms. 2 is considered as one term and 2cis considered as the second term.

Therefore, it is a binomial expression.

Hence, $2c+2$is not a monomial expression.
