Use scientific notation to determine which of these numbers has the least value: 123,893, 31,892, ог 12,786. Write your answer in scientific notation, expressed to the exact decimal place. (1 point)

Answer 1

To determine which number has the least value, we 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

Therefore, 12,786 in scientific notation is 1.2786 x 10^4, which has the least value among the given numbers.
