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.

Answer 1

To determine which number has the greatest value, we can rewrite the numbers in scientific notation and compare their coefficients.

654,987,034 can be written as 6.54987034 × 10^8
645,897,430 can be written as 6.4589743 × 10^8
546,789,340 can be written as 5.4678934 × 10^8

Comparing the coefficients, we can see that 6.54987034 × 10^8 is the largest value.

Therefore, the number 654,987,034 has the greatest value, expressed in scientific notation as 6.54987034 × 10^8.
