<u>Answer:</u>
The correct answer option is 
.
<u>Step-by-step explanation:</u>
We are given the following expression and we are to evaluate it when 
and 
:
![[\frac{3^2a^{-2}}{3a^{-1}} ]^k](https://tex.z-dn.net/?f=%5B%5Cfrac%7B3%5E2a%5E%7B-2%7D%7D%7B3a%5E%7B-1%7D%7D%20%5D%5Ek)
Substituting the given values of 
and 
to get:
![[\frac{3^2(5)^{-2}}{3(5)^{-1}} ]^{-2}](https://tex.z-dn.net/?f=%5B%5Cfrac%7B3%5E2%285%29%5E%7B-2%7D%7D%7B3%285%29%5E%7B-1%7D%7D%20%5D%5E%7B-2%7D)
89/100 because the percent is out of 100 so it’s the same thing as 89/100
⓵ You run 1 ¾ miles. You can decide to work with fractions, but I find it easier to work with decimals :
¾ = 3 ÷ 4 = 0,75
1 mile + 0,75 mile = 1,75 miles
⓶ Your friend runs 4 times as far as you do, wich means that he runs 1,75 miles times four :
1,75 x 4 = 7 miles
So your final answer is : Your friend runs 7 miles each day.
I hope this helped, if there’s anything just let me know! ☻
