Understanding Monomials
Monomials are single-term algebraic expressions that consist of numbers, variables, or both, multiplied together. In this case, we have the monomials "0" and "8mnr²".

Step 1: Identifying the Monomials
- The first monomial is **0**.
- The second monomial is **8mnr²**, where:
- **8** is the coefficient.
- **m**, **n**, and **r** are variables.
- **r²** indicates that the variable **r** is squared.

Step 2: Multiplying the Monomials
To find the product of the two monomials, apply the multiplication rule:
- When multiplying any number (or monomial) by **0**, the result is always **0**.
Thus, the product of the monomials will be:
- **0 × 8mnr² = 0**

Conclusion
- The product of the monomials **0** and **8mnr²** is simply **0**.
- This is a fundamental property of multiplication that applies universally: anything multiplied by zero results in zero.

Key Takeaways
- **Monomials** consist of coefficients and variables.
- **Multiplication with zero** always results in zero.
By understanding these concepts, you can handle similar problems involving monomials confidently!
