A. 4 × 10^3
B. 10^3 × 2^4
C. 10^7
D. 10^7 × 24
E. 10^11

For this problem, it's probably easier to just write out the numbers:

10$$^3$$ =

Today:=1000
x 2 in 3 months = 2000
x 2 (+3 months) = 4000
x 2 (+3 months) = 8000
x 2 (+3 months) = 16,000

From answer choices: 16,000 = 16 x 1000 = 2$$^4$$ x 10$$^3$$ -- or 10$$^3$$ x 2$$^4.$$ Answer: B
