Question - Mathematical Expression Rounding in Scientific Notation

Solution:

The image shows a mathematical expression where a number is rounded in scientific notation. The original number is 10470000, and it is being rounded to one significant figure, becoming $$1 \times 10^7$$. The steps shown are correct. The expression starts with the number 10470000 and then brackets are placed to separate the significant figure (1) from the rest of the number (0470000). Next, the expression is rewritten with the rounded number as $$1 \times 10^7$$. The chinese character "万" translates to "ten thousand" in English, which is part of the Chinese numbering system where 10,000 is a basic unit.
