- The following problem is from both the 2021 Fall AMC 10B #5 and 2021 Fall AMC 12B #4, so both problems redirect to this page.
Problem
Let 
. Which of the following is equal to 
Solution 1
We have ![\[n=8^{2022}= \left(8^\frac{2}{3}\right)^{3033}=4^{3033}.\]](http://latex.artofproblemsolving.com/f/f/8/ff8f511842bf3275a1d48df6d5f8adcd18102756.png)
Therefore, ![\[\frac{n}4=\boxed{\textbf{(E)} \: 4^{3032}}.\]](http://latex.artofproblemsolving.com/4/4/c/44cf34fd04107d751424dd4df3f40daae9b744e1.png)
