Evaluate the following: `\ (x+sqrt(x^2-1))^6+(x-sqrt(x^2-1))^6`

Explanation

To evaluate the expression \( (x + \sqrt{x^2 - 1})^6 + (x - \sqrt{x^2 - 1})^6 \), we can use the Binomial Theorem.

### Step-by-Step Solution:

1. **Identify the Terms**:
Let \( a = \sqrt{x^2 - 1} \). The expression can be rewritten as:
\[
(x + a)^6 + (x - a)^6
