Sure, I can help you with monomial expressions!
A monomial expression is a mathematical expression that consists of only one term, with variables raised to non-negative integer exponents. To determine if an expression is a monomial, we need to check if it meets these criteria.
Let's start with the first question:
Is 7(m - 2) a monomial expression?
To determine this, we need to simplify the expression and see if it contains multiple terms or variables raised to negative exponents.
Simplifying 7(m - 2), we get 7m - 14.
Since there is only one term and no negative exponents, 7(m - 2) is indeed a monomial expression.
Now, onto the second question:
Is 3mnp a monomial expression?
We can observe that there are no addition or subtraction signs involved in the expression, so there is only one term.
Additionally, we do not have any negative exponents in this expression.
Therefore, 3mnp is a monomial expression.
In summary:
- 7(m - 2) is a monomial expression.
- 3mnp is also a monomial expression.
