We can use the fact that (a - b)/c = a/c + b/c

So, (4^13 - 4^12)/(4^11) = (4^13)/(4^11) - (4^12)/(4^11)
= 4^2 - 4^1 [after applying the rules for dividing powers]
= 16 - 4
= 12

Answer: D

Cheers,
Brent

There are two important "tricks" in this quesiton.

1) You have to use the rule for "distributing a factor" (or whatever is called).

2) You have to realize that the difference between 4^13 and 4^11 is two times 4.
