10(15)/10(−3)

Answer 1

To determine which expression leaves you with the largest number on the number line, we can simplify each option:

1. **\( \frac{10^8}{10^{18}} \)**:
\[
\frac{10^8}{10^{18}} = 10^{8 - 18} = 10^{-10} \approx 0.0000000001
\]

2. **\( (10^2)^8 \)**:
\[
(10^2)^8 = 10^{2 \times 8} = 10^{16}
\]

3. **\( 10^5 \cdot 10^{-4} \cdot 10^{-5} \)**:
\[
10^5 \cdot 10^{-4} \cdot 10^{-5} = 10^{5 - 4 - 5} = 10^{-4} = 0.0001
\]

4. **\( \frac{10^{15}}{10^{-3}} \)**:
\[
\frac{10^{15}}{10^{-3}} = 10^{15 - (-3)} = 10^{15 + 3} = 10^{18}
\]

Now we can compare the results:

1. \( 10^{-10} \approx 0.0000000001 \)
2. \( 10^{16} \)
3. \( 10^{-4} = 0.0001 \)
4. \( 10^{18} \)

The largest value is clearly \( 10^{18} \).

Therefore, the expression that leaves you with the largest number on the number line is:

**\( \frac{10^{15}}{10^{-3}} \)**
