Question

Use scientific notation to determne which of these numbers has the least value
8.97 X 10^7
9.87 X 10^6
7.89 X 10^8

Answer 1

To compare the numbers in scientific notation:

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

Let's express them in standard form:

1. \( 8.97 \times 10^7 = 89,700,000 \)
2. \( 9.87 \times 10^6 = 9,870,000 \)
3. \( 7.89 \times 10^8 = 789,000,000 \)

Now we can see the values:

- \( 89,700,000 \)
- \( 9,870,000 \)
- \( 789,000,000 \)

The smallest value is \( 9.87 \times 10^6 \), which is \( 9,870,000 \).
