Answer

To find the order of magnitude of the number 4,571,100 (or 45,71,100), we can follow these steps:

### Step-by-Step Solution:

1. **Convert the Number to Scientific Notation**:
- The first step is to express the number in scientific notation. This means we need to write it in the form of \( a \times 10^n \), where \( 1 \leq a < 10 \).
- For the number 4,571,100, we can write it as:
\[ 4.571100 \times 10^6 \]

2. **Identify the Exponent**:
- In the scientific notation \( 4.571100 \times 10^6 \), the exponent of 10 (which is 6) indicates the order of magnitude of the number.
- Therefore, the order of magnitude of 4,571,100 is:
\[ 6 \]

3. **Final Answer**:
- The order of magnitude of 4,571,100 meters is:
\[ 6 \]
