Problem
Which of the following values is largest?
Solution 1
We will compute each expression.
A) 
B) 
C) 
D) 
E) 
Ordering these, we get 
. Out of these, 
is the largest number and option 
adds up to . Therefore, the answer is 
.
- SBose
Solution 2
We immediately see that every one of the choices, except for A and D, has a number multiplied by 
. This will only make the expression's value smaller. We are left with A and D, but in D, 
is multiplied by 
to get , whereas in answer choice A, we get 
out of and , instead of . Therefore, is your answer.
