3.47866×107
3.47866 times 10 superscript 7 baseline

3.487×107
3.487 times 10 superscript 7 baseline

34,870,000
34,870,000

3.47866×106

Answer 1

To compare the numbers 3,478,660; 34,870,000; and 34,786,600 using scientific notation, we will first convert each number to scientific notation:

1. **3,478,660** = \(3.47866 \times 10^6\)
2. **34,870,000** = \(3.487 \times 10^7\)
3. **34,786,600** = \(3.47866 \times 10^7\)

Now we can compare the scientific notation:

- \(3.47866 \times 10^6\) (this is less than both of the next two)
- \(3.487 \times 10^7\)
- \(3.47866 \times 10^7\)

Since both \(3.487 \times 10^7\) and \(3.47866 \times 10^7\) are multiplied by \(10^7\), we can just compare the \(3.487\) and \(3.47866\) coefficients.

Since \(3.487 > 3.47866\), we conclude that:

**The greatest value is:** **34,870,000** (which is \(3.487 \times 10^7\)).
