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.
