In this post, we will look at what monomials are, what their components are and what properties they have.
Let’s start by looking at what a monomial is:
A monomial is a combination of numbers and letters related by only multiplication and the exponents of the letters can only be natural numbers.
Is a monomial because it is a combination of numbers and letters related to each other only by multiplication and the exponent that appears is a natural number.
-2m 5 + m 3
It is not a monomial because both addition and subtraction appear.
In the following exercise, decide if the algebraic expressions are monomials or not:
The Parts of a Monomial:
- Coefficient: The number the letters are multiplied by.
- Literal part: the letters displayed in the monomial with exponents.
- Degree: The sum of the exponents that the monomial has.
- Variable: Each of the letters in the monomial.
For example, let’s look at the parts of the following monomial:
- Coefficient: -2 is the number that accompanies the literal part.
- Literal part: ab 2
- Degree: 1 + 2 = 3. The degree of the monomial is 3.
- Variable: a, b. They are the two letters that appear in the monomial.
What are two similar monomials?
Two monomials are similar when they have exactly the same literal part.
For example, a similar monomial for one that we’ve seen before, -2ab 2, would be any which had the same literal part: ab 2
Like the monomials: -6ab 2 , 5AB 2 , 18ab 2 , ab 2 …
Now, I propose that you connect the monomials in the left column with their similar monomials in the right column.
