Monomial Simplification and Properties

This video tutorial covers the simplification of rational expressions, focusing on monomials. It begins with an introduction to rational expressions and monomials, explaining that monomials are single terms without pluses or minuses. The tutorial then demonstrates how to simplify these expressions by focusing on numerical parts and exponents. Advanced techniques for handling variables are also discussed, with examples provided to illustrate the process. The lesson concludes with a final example and instructions for students to complete a worksheet.

What is a monomial?

• A fraction with a numerator and denominator

• A single term without pluses or minuses

• A polynomial with at least two terms

• A term with multiple variables and operations

When simplifying monomial expressions, what should you focus on first?

• The exponents

• The variables

• The entire expression

• The numerical part
