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)
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.
To determine which of the given numbers has the least value, we can write each number in scientific notation and compare their exponents.
98,749,000,990.000 can be written in scientific notation as 9.874900099 × 10^10 (rounded to 2 decimal places).
89,987,000 can be written in scientific notation as 8.9987 × 10^7 (rounded to 2 decimal places).
Comparing the exponents, we can see that 8.9987 × 10^7 (89,987,000) has a smaller exponent (7) compared to 9.874900099 × 10^10 (98,749,000,990.000). Therefore, 89,987,000 has the least value among the given numbers in scientific notation.
To determine which of these numbers has the least value using scientific notation, we need to express each number in scientific notation and compare the exponents. The number with the lowest exponent will have the least value.
Let's write each number in scientific notation:
1. 98 749 000 990.000 can be written as 9.8749000099 x 10^10
2. 89 987 000 can be written as 8.9987000 x 10^7
To compare these numbers, we consider the exponents. The number with the lower exponent has the least value.
In this case, the exponent of the second number, 8.9987000 x 10^7, is smaller than the exponent of the first number, 9.8749000099 x 10^10.
Therefore, the number 89 987 000 has the least value when expressed in scientific notation.
