ty for the points general!
Answer: a) 1024, b) 1, c) 64 and d) 0.125.
Step-by-step explanation:
Since we have given that
(a) 
As we know that

So, it becomes,

(b) 
As we know that


c) 
As we know that

(d) ![[(8^{-1})(8^{\frac{2}{3}})]^3](https://tex.z-dn.net/?f=%5B%288%5E%7B-1%7D%29%288%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%29%5D%5E3)
As we know that
![[(8^{-1})(8^{\frac{2}{3}})]^3\\\\=[8^{-1+\frac{2}{3}}]^3\\\\=[8^{\frac{-1}{3}}]^3\\\\=8^{-1}\\\\=\dfrac{1}{8}=0.125](https://tex.z-dn.net/?f=%5B%288%5E%7B-1%7D%29%288%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%29%5D%5E3%5C%5C%5C%5C%3D%5B8%5E%7B-1%2B%5Cfrac%7B2%7D%7B3%7D%7D%5D%5E3%5C%5C%5C%5C%3D%5B8%5E%7B%5Cfrac%7B-1%7D%7B3%7D%7D%5D%5E3%5C%5C%5C%5C%3D8%5E%7B-1%7D%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B8%7D%3D0.125)
Hence, a) 1024, b) 1, c) 64 and d) 0.125.
Because there are 4 people and all bought the same things you multiple 4(4+1+2)=4x7=28 So the total cost is $28
