Use scientific notation to determine which of these numbers has the least value: 123,893, 31,892, or 12,786. Write your answer in scientific notation, expressed to the exact decimal place.
whats the answer?
To determine which of the three numbers has the least value, we need to write them in scientific notation and compare their magnitude.
123,893 can be written in scientific notation as 1.23893 x 10^5.
31,892 can be written in scientific notation as 3.1892 x 10^4.
12,786 can be written in scientific notation as 1.2786 x 10^4.
Comparing the exponents, we see that 10^4 is smaller than 10^5. Therefore, the number 12,786 (expressed as 1.2786 x 10^4) has the least value in scientific notation.
To determine which number has the least value using scientific notation, we need to convert each number to scientific notation and compare their magnitudes.
Let's convert each number to scientific notation:
123,893 = 1.23893 x 10^5
31,892 = 3.1892 x 10^4
12,786 = 1.2786 x 10^4
To compare their magnitudes, we compare the exponents. The lower the exponent, the smaller the number.
Comparing the exponents, we see that:
1.23893 x 10^5 > 3.1892 x 10^4 > 1.2786 x 10^4
Therefore, 12,786 has the least value among the given numbers in scientific notation.
Expressed in scientific notation, the number 12,786 is 1.2786 x 10^4.
To determine the least value among these numbers, we need to convert them into scientific notation.
123,893 = 1.23893 * 10^5
31,892 = 3.1892 * 10^4
12,786 = 1.2786 * 10^4
Comparing the exponential values, 10^4 is the least among them. Therefore, the number 12,786 has the least value in scientific notation.
