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 $\frac{5k}{10}$, contains a constant $\frac{5}{10}$ and a variable ‘k’.

By the definition of monomial, $\frac{5k}{10}$is considered as one single term where $\frac{5}{10}$is the coefficient and k is the literal part.

Hence, $\frac{5k}{10}$is a monomial.
