Question: 112
1. 
- A. The quantity in Column A is greater.
- B. The quantity in Column B is greater.
- C. The two quantities are equal.
- D. The relationship cannot be determined from the information given.
Correct Answer: A
Explanation:
The answer is A
Column A: 1.5 × 105 + 2.6 × 10-3 = 150,000 + 0.0026 = 150,000.0026. Column B: 9.8 × 104 + 8.7 × 10-2 = 98,000 + 0.087 = 98,000.087.
The negative exponents will have minimal effect. Raising 10 to the fifth power results in a greater value than does raising 10 to the fourth power.
