To compare the numbers using scientific notation:
- 3,478,660 can be expressed as 3.47866 × 10^6.
- 34,870,000 can be expressed as 3.487 × 10^7.
- 34,786,600 can be expressed as 3.47866 × 10^7.
Now, let's compare the values:
- 3.47866 × 10^6 (which is 3,478,660) is the smallest because it has the smallest exponent.
- 3.487 × 10^7 (which is 34,870,000) has a larger coefficient and the larger exponent than the first, so it is greater.
- 3.47866 × 10^7 (which is 34,786,600) is slightly less than 34,870,000 because the coefficient 3.47866 is less than 3.487.
Thus, the number with the greatest value is 34,870,000.
