To determine which expression leaves you with the largest number on the number line, we can simplify each option:
-
\( \frac{10^8}{10^{18}} \): \[ \frac{10^8}{10^{18}} = 10^{8 - 18} = 10^{-10} \approx 0.0000000001 \]
-
\( (10^2)^8 \): \[ (10^2)^8 = 10^{2 \times 8} = 10^{16} \]
-
\( 10^5 \cdot 10^{-4} \cdot 10^{-5} \): \[ 10^5 \cdot 10^{-4} \cdot 10^{-5} = 10^{5 - 4 - 5} = 10^{-4} = 0.0001 \]
-
\( \frac{10^{15}}{10^{-3}} \): \[ \frac{10^{15}}{10^{-3}} = 10^{15 - (-3)} = 10^{15 + 3} = 10^{18} \]
Now we can compare the results:
- \( 10^{-10} \approx 0.0000000001 \)
- \( 10^{16} \)
- \( 10^{-4} = 0.0001 \)
- \( 10^{18} \)
The largest value is clearly \( 10^{18} \).
Therefore, the expression that leaves you with the largest number on the number line is:
\( \frac{10^{15}}{10^{-3}} \)
