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. (1 point)
To convert the numbers to scientific notation, we need to move the decimal point so that there is only one non-zero digit to the left of the decimal point. The number with the greatest value will have the greatest coefficient (the number to the left of the decimal point).
654,987,034 in scientific notation is 6.54987034 x 10^8
645,897,430 in scientific notation is 6.4589743 x 10^8
546,789,340 in scientific notation is 5.4678934 x 10^8
Therefore, the number with the greatest value is 654,987,034 in scientific notation, expressed to the exact decimal place.
