Question

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?

Answer 1

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.
