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. (point)
To determine which of these numbers has the least value, we can convert them into scientific notation and compare their magnitudes.
98,789,000 can be written in scientific notation as 9.8789 × 10^7
987,890,000 can be written in scientific notation as 9.8789 × 10^8
89,987,000 can be written in scientific notation as 8.9987 × 10^7
From these notations, we can see that 8.9987 × 10^7 has the least value.
To determine which number has the least value, we need to compare them in 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 numbers, we can see that 9.8789 x 10^7 is the least value because it has a smaller exponent than the other two numbers.
To determine which of the given numbers has the least value using scientific notation, we need to write them all in scientific notation form. In scientific notation, we express a number as the product of a decimal number between 1 and 10 (mantissa) and a power of 10 (exponent).
Let's 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
Comparing these numbers, we can see that the one with the least value is 8.9987 × 10^7 (89,987,000 in scientific notation).
Therefore, the number 89,987,000 has the least value among the given options in scientific notation, expressed to the exact decimal place.
