Question
Use scientific notation to determine which of these numbers has the least value: 98,789,000; 987,890,000; or 89,987,000. Write your answer in scientific notation, expressed to the exact decimal place.(1 point)
To determine which number has the least value, we need to write these numbers in scientific notation and compare the exponents.
98,789,000 can be written as 9.8789 x 10^7
987,890,000 can be written as 9.8789 x 10^8
89,987,000 can be written as 8.9987 x 10^7
Comparing the exponents, we can see that 9.8789 x 10^7 is the least value.
