1. Objectives: Standard 15.0 I will find the LCM (Least Common Multiple) of the given denominators I will simplify the rational expressions by using the LCM of the given denominators

2. Review 1 Important: When finding LCM, take the highest exponent of the same factor.

3. Review 2 Important: When finding LCM, multiply the factor even it is not a common factor for both given numbers.
