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 convert these numbers to scientific notation, we need to move the decimal point until we have a number between 1 and 10, and multiply it by a power of 10.
a) 98,789,000 = 9.8789 x 10^7
b) 987,890,000 = 9.8789 x 10^8
c) 89,987,000 = 8.9987 x 10^7
To determine which number has the least value, we compare the numerical values of the coefficients:
9.8789 x 10^7 > 8.9987 x 10^7
Thus, the number 89,987,000 has the least value when expressed in scientific notation.
To determine which of the numbers has the least value, we need to convert them into scientific notation.
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 these three numbers, we can see that the number 9.8789 x 10^7 (98,789,000) has the least value in scientific notation.
To determine which number has the least value, we can compare them using scientific notation. Scientific notation is a way of expressing very large or very small numbers using powers of 10.
Let's convert each of the given numbers to scientific notation:
98,789,000 = 9.8789 x 10^7
987,890,000 = 9.8789 x 10^8
89,987,000 = 8.9987 x 10^7
Now, we can see that 9.8789 x 10^7 is the smallest number because it has the lowest power of 10. Therefore, the number 98,789,000 has the least value in scientific notation.
