To convert the numbers 3,478,660; 34,870,000; and 34,786,600 into scientific notation, we do the following:
-
3,478,660:
- Move the decimal point 6 places to the left: \(3.47866 \times 10^6\)
-
34,870,000:
- Move the decimal point 7 places to the left: \(3.487 \times 10^7\)
-
34,786,600:
- Move the decimal point 7 places to the left: \(3.47866 \times 10^7\)
Now we can summarize the scientific notation of the numbers:
- \(3,478,660 = 3.47866 \times 10^6\)
- \(34,870,000 = 3.487 \times 10^7\)
- \(34,786,600 = 3.47866 \times 10^7\)
To compare the numbers, we have to look at both the coefficient and the exponent in scientific notation.
- \(3.47866 \times 10^6\) has \(10^6\) (which means it is much smaller than numbers with \(10^7\)).
- \(3.487 \times 10^7\) and \(3.47866 \times 10^7\) both have \(10^7\), so we compare the coefficients:
- \(3.487\) (from \(34,870,000\)) is greater than \(3.47866\) (from \(34,786,600\)).
Therefore, the greatest number is \(34,870,000\), or \(3.487 \times 10^7\) in scientific notation.
So, the answer is: 34,870,000 has the greatest value.
