Use scientific notation to determine which of these numbers has the greatest value: 654,987,034; 645,897,430; or 546,789,340. Write your answer in scientific notation, expressed to the exact decimal place
To determine the greatest value among these numbers, we need to express them in scientific notation and compare their magnitudes.
654,987,034 = 6.54987034 x 10^8
645,897,430 = 6.45897430 x 10^8
546,789,340 = 5.46789340 x 10^8
Comparing the exponents, we can see that all three numbers have the same magnitude of 10^8. Therefore, to determine the greatest value, we would need to compare the coefficients.
Among the coefficients, 6.54987034 is the greatest value.
Thus, the number that has the greatest value is 6.54987034 x 10^8.
