Use scientific notation to determine which of these numbers has the least value 98 749 000 990.000 89 987 000 Write your answer in scientific notation expressed to the exact decimal place (2 print)

Answer 1

The numbers given are:

98 749 000 = 9.8749000 x 10^7
990.000 = 9.90 x 10^2
89 987 000 = 8.9987000 x 10^7

In scientific notation, the number with the smallest exponent is the smallest number. So, the number 990.000 (expressed as 9.90 x 10^2 in scientific notation) is the smallest among the three.
