Question

Use scientific notation to determine which of these numbers has the
least value.
Circle your answer.
8.97 X 10^7
9.87 X 10^6
7.89 X 10^8

Answer 1

To determine which of the numbers has the least value, we can express each number in scientific notation with the same exponent for easier comparison.

1. \( 8.97 \times 10^7 = 89.7 \times 10^6 \)
2. \( 9.87 \times 10^6 = 9.87 \times 10^6 \)
3. \( 7.89 \times 10^8 = 789 \times 10^6 \)

Now we can compare these values:

- \( 89.7 \times 10^6 \)
- \( 9.87 \times 10^6 \)
- \( 789 \times 10^6 \)

Since \( 9.87 \times 10^6 \) is the smallest value when compared to \( 89.7 \times 10^6 \) and \( 789 \times 10^6 \), the number with the least value is:

**9.87 X 10^6**.
