Answers
Answer
use scientific notation to determine which of these numbers has the least value 86,659,000; 867,450,000; or 86,423,000. write your answer in scientific notation, expressed to the exact decimal place
Answer
place the numbers in descending order.
4.3x10^-5 ; 6.4x10^-6 ; 4.3x10^-6 ; 6.4x10^-4
4.3x10^-5 ; 6.4x10^-6 ; 4.3x10^-6 ; 6.4x10^-4

To determine which of the numbers has the least value, we can express all of them in scientific notation.
86,659,000 = 8.6659 x 10^7
867,450,000 = 8.6745 x 10^8
86,423,000 = 8.6423 x 10^7
By comparing the exponents in their scientific notations, we see that 8.6659 x 10^7 has the least value.
86,659,000 = 8.6659 x 10^7
867,450,000 = 8.6745 x 10^8
86,423,000 = 8.6423 x 10^7
By comparing the exponents in their scientific notations, we see that 8.6659 x 10^7 has the least value.

To place the numbers in descending order, we need to compare the coefficients first and then the exponents if the coefficients are equal.
Starting with the coefficients:
6.4 x 10^-6
4.3 x 10^-6
Next, comparing the exponents:
6.4 x 10^-6
4.3 x 10^-6
Lastly,
6.4 x 10^-4
Therefore, the numbers in descending order are:
6.4 x 10^-4
6.4 x 10^-6
4.3 x 10^-6
4.3 x 10^-5
Starting with the coefficients:
6.4 x 10^-6
4.3 x 10^-6
Next, comparing the exponents:
6.4 x 10^-6
4.3 x 10^-6
Lastly,
6.4 x 10^-4
Therefore, the numbers in descending order are:
6.4 x 10^-4
6.4 x 10^-6
4.3 x 10^-6
4.3 x 10^-5
