1. The problem is to evaluate whether the provided solution is correct and to identify four strengths of the solution. 2. To verify correctness, we check each step of the solution for logical consistency, correct application of formulas, and accurate calculations. 3. Strength 1: The solution clearly states the problem and the goal, which helps in understanding the context. 4. Strength 2: It uses appropriate formulas and explains the reasoning behind each step, aiding comprehension. 5. Strength 3: Intermediate steps are shown in detail, allowing verification and learning. 6. Strength 4: The explanation is learner-friendly, with plain language and line breaks for readability. 7. Without the specific solution text, we cannot confirm exact correctness, but these strengths indicate a well-structured approach.
