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 convert each number to scientific notation.
- 98,789,000 = 9.8789 × 10^7
- 987,890,000 = 9.8789 × 10^8
- 89,987,000 = 8.9987 × 10^7
From these values, we can see that 9.8789 × 10^7 = 98,789,000 has the least value.
To compare the values of the numbers using scientific notation, we need to rewrite the numbers in scientific notation.
The number 98,789,000 can be written in scientific notation as 9.8789 × 10^7.
The number 987,890,000 can be written in scientific notation as 9.8789 × 10^8.
The number 89,987,000 can be written in scientific notation as 8.9987 × 10^7.
To determine which number has the least value, we compare the exponents. In this case, 10^7 is smaller than both 10^8 and 10^7, so the number 9.8789 × 10^7, or 98,789,000 in scientific notation, has the least value.
To determine which of these numbers has the least value using scientific notation, we need to convert each number into scientific notation and compare their exponents.
Let's begin by converting each number into scientific notation:
98,789,000 = 9.8789 × 10^7
987,890,000 = 9.8789 × 10^8
89,987,000 = 8.9987 × 10^7
Now, we can compare the exponents of these numbers:
9.8789 × 10^7
9.8789 × 10^8
8.9987 × 10^7
Comparing the exponents, we can see that the number with the least value is 8.9987 × 10^7.
Therefore, the answer is 8.9987 × 10^7.
