use scientific notation to determine which of these numbers has the least value 98,789,000; 987,890,000; Or 80,987.000. write your answer in scientific notation expressed to extract decimal place

To determine which number has the least value in scientific notation, we need to convert the numbers into scientific notation and compare the exponents.

98,789,000 = 9.8789 x 10^7
987,890,000 = 9.8789 x 10^8
80,987.000 = 8.0987 x 10^4

Comparing the exponents, we see that 8.0987 x 10^4 has the least value in scientific notation, as the exponent is smaller than the other two numbers.
