I'm slightly confused about this question:
Suppose that you memorize a list of 100 German vocabulary words. Each week you forget 1/8 of the words you knew the previous week. The number of vocabulary words (V) that you remember after t weeks can be modeled by:
V=100(7/80)^t
Find the ratio of the number of words you remember in week 3 to the number of words you remember in week 9. Express your answer in simplest exponent form.
What is simplest exponent form?
I start with the ratio of:
100(7/8)^3:100(7/8)^9
do I cancel out everything except the 3:9?
