which expression leaves you with the largest number on the number line.

A. (10^2)^8
B. 10^5 ∙ 10^-4 ∙ 10^-5
C. 10^15/10^-3
D. 10^8/10^18

To determine which expression leaves the largest number on the number line, we need to simplify each expression and compare the resulting numbers.

A. (10^2)^8 = 10^16

B. 10^5 ∙ 10^-4 ∙ 10^-5 = 10^(5-4-5) = 10^-4

C. 10^15/10^-3 = 10^(15-(-3)) = 10^18

D. 10^8/10^18 = 10^(8-18) = 10^-10

Comparing the numbers:

10^16, 10^-4, 10^18, 10^-10

The expression that leaves the largest number on the number line is C. 10^15/10^-3 = 10^18.
