Ignore the constraint that a must be a positive integer.vinay1983 wrote:
The correct answer choice must work for ANY VALUE of a.
Let a = 1/2.
Then:
3^(2a) + (36^a) / (2^(2a)) = 3 + (√36)/2 = 3 + 3 = 6. This is our target.
Now plug a = 1/2 into the answers to see which yields our target of 6.
A quick scan reveals that only E works:
2 * 9^a = 2 * √9 = 2*3 = 6.
The correct answer is E.
