The correct Answer is:
To identify like terms from the given expressions, we need to look for terms that have the same variables raised to the same powers. Let's analyze the terms one by one. ### Step-by-Step Solution: 1. **List the Terms**: The given terms are: - \( abc \) - \( ab^2c \) - \( acb^2 \) - \( c^2ab \) - \( b^2ac \) - \( a^2bc \) - \( cab^2 \) 2. **Identify the Variables and Their Powers**: - \( abc \): \( a^1b^1c^1 \) - \( ab^2c \): \( a^1b^2c^1 \) - \( acb^2 \): \( a^1b^2c^1 \) (same as \( ab^2c \)) - \( c^2ab \): \( a^1b^1c^2 \) - \( b^2ac \): \( a^1b^2c^1 \) (same as \( ab^2c \) and \( acb^2 \)) - \( a^2bc \): \( a^2b^1c^1 \) - \( cab^2 \): \( a^1b^2c^1 \) (same as \( ab^2c \), \( acb^2 \), and \( b^2ac \)) 3. **Group the Like Terms**: - The terms \( ab^2c \), \( acb^2 \), \( b^2ac \), and \( cab^2 \) all have the same variables with the same powers: \( a^1b^2c^1 \). - The term \( abc \) is unique with \( a^1b^1c^1 \). - The term \( c^2ab \) is unique with \( a^1b^1c^2 \). - The term \( a^2bc \) is unique with \( a^2b^1c^1 \). 4. **Final List of Like Terms**: - Like terms: \( ab^2c \), \( acb^2 \), \( b^2ac \), \( cab^2 \) - Unique terms: \( abc \), \( c^2ab \), \( a^2bc \) ### Conclusion: The like terms in the given expressions are: - \( ab^2c \) - \( acb^2 \) - \( b^2ac \) - \( cab^2 \)
