If the distance between the foci of a hyperbola is `16` and its eccentricity is `sqrt(2)` , then obtain its equation.

Explanation

To find the equation of the hyperbola given the distance between the foci and the eccentricity, we can follow these steps:

### Step 1: Identify the distance between the foci and eccentricity
The distance between the foci of a hyperbola is given as \(16\) and the eccentricity \(e\) is given as \(\sqrt{2}\).

### Step 2: Use the formula for the distance between the foci
The distance between the foci of a hyperbola is given by the formula:
\[
