Difficulty: Easy
Correct Answer: 3a^2 b c
Explanation:
Introduction / Context:
This is a straightforward monomial simplification using exponent subtraction for like bases and coefficient division. Such manipulations are routine in algebraic simplification before factorization or substitution steps.
Given Data / Assumptions:
Concept / Approach:
For like bases, a^m / a^n = a^(m−n). Also divide numeric coefficients: 6/2 = 3.
Step-by-Step Solution:
Verification / Alternative check:
Plug small values (e.g., a=b=c=2): LHS = 6*8*8*4 / (2*2*4*2) = 1536 / 32 = 48; RHS = 3*(4)*2*2 = 48. Matches.
Why Other Options Are Wrong:
Common Pitfalls:
Adding exponents during division or miscounting one of the variables’ exponents.
