Problem
What is the correct ordering of the three numbers, 
, 
, and 
?
Solution 1
Use brute force.
Therefore, 
is the answer.
Solution 
Since all of the exponents are multiples of four, we can simplify the problem by taking the fourth root of each number. Evaluating we get 
, 
, and 
. Since 
, it follows that 
is the correct answer.
