Question

If the product of n positive integers is nn, then their sum is:

Answer 1

Never less than n2

Explanation:
Clearly, since the given integers are positive, their sum can't be negative. Also, since the numbers are all integers their sum can't be a fraction. Let's take 1, 3 and 9. The product of these three integers is 27 = 33. This can also be written as nn where n=3. As we can see, the sum of these 3 integers is not equal to 3. Therefore, we are left with the fourth option.
