正确答案 · Correct Answer
B
解析 · Solution
Solution 1
The first hieroglyph is worth 10,000, the next 4 are worth , the next 2 are worth , and the last 3 are worth . Therefore, the answer is 10,000 + 400 + 20 + 3 = 10,423
1 ⋅ 10 4 + 0 ⋅ 10 3 + 4 ⋅ 10 2 + 2 ⋅ 10 1 + 3 ⋅ 10 0 = 10423 From a first inspection, you may notice that there is no thousands hieroglyph. The only option with zero in the thousands place is 10,423
