Here is the complete question
ack wants to fined out which can pineapples is the best buy. He has a choice of four different -sized cans. Which can has the lowest unit price per ounce?
A. 8 ounce for $ 1.44
B. 6 ounce for $ 1. 14

D. 10 ounce for $ 1.62
unit price = price / total ounces
$1.44 / 8 = $0.18
$1.14 / 6 = $0.19
$2.88 / 18 = $0.16
$1.62 / 10 = 0.162
the lowest is 18 ounce for $ 2.88
Step-by-step explanation:
We will prove by contradiction. Assume that 
is an odd prime but n is not a power of 2. Then, there exists an odd prime number p such that 
. Then, for some integer 
,
Therefore
Here we will use the formula for the sum of odd powers, which states that, for 
and an odd positive number 
,
Applying this formula in 1) we obtain that
.
Then, as 
we have that 
is not a prime number, which is a contradiction.
In conclusion, if is an odd prime, then n must be a power of 2.
