No,the number of coffee sold per week does not fully represent the number of workers per week
Step-by-step explanation:
A sample that represents a population should be one that accurately reflects the population. If you have the data the shows the number of workers per day then you could calculate the number of workers that facilitate the sell of a certain amount of coffee per day. In this case, the sample could represent the amount of coffee sold for the week but not really the workers that were engaged that week.

The problem is asking you to simplify the exponents. When you multiply two or more powers with the same base, the exponents can be added and subtracted. In this case, the base is 7.
![7^6*7*7^{-4}](https://tex.z-dn.net/?f=7%5E6%2A7%2A7%5E%7B-4%7D)
7 can also be written as
![7^1](https://tex.z-dn.net/?f=7%5E1)
.
![7^6*7^1*7^{-4} = 7 ^{(6+1-4)} = 7^3](https://tex.z-dn.net/?f=7%5E6%2A7%5E1%2A7%5E%7B-4%7D%20%3D%207%20%5E%7B%286%2B1-4%29%7D%20%3D%207%5E3)
The answer would be 7³ if you kept the exponent, or 343 if you simplified further.
