Monomials

# Identify monomials

A Monomial is an algebraic expression containing only one term. For example:3xy2

• A monomial can be a constant number or a variable expression.
• A monomial should not have negative and fractional exponents.
• Monomials cannot include addition or subtraction.

Is 3m2 a monomial?

A monomial is a number, a variable, or a product of numbers and variables.
3m2 is the product of a number and variables. It does not include addition. So, 3m2 is a monomial.

Is 3x2+1 a monomial?

A monomial is a number, a variable, or a product of numbers and variables.
Monomials cannot include addition or subtraction.
3x2+1 is the sum of two monomials. So, 3x2+1 is not a monomial.
