# You need 3 things for maths.

Algebra Level 5

Let $$n$$ be a non-zero real number (not necessarily positive). Find the minimum value of

$\prod_{i = 1}^{8}(n^{2^{i}} + 1) + \prod_{i = 1}^{8}(\frac{1}{n^{2^{i}}} + 1).$

According to my thoughts, you need 3 things for solving math problems:

1. Knowledge

2. Imagination

3. Solve this problem to figure that one out.

Hint: The third word starts with $$T$$ and ends with $$S$$. It may depend on each person whether this hint has actually helped or not.
