Simplify : `a^(6)-b^(6)`

Explanation

To simplify the expression \( a^6 - b^6 \), we can follow these steps:

### Step 1: Recognize the difference of cubes
The expression \( a^6 - b^6 \) can be rewritten as \( (a^2)^3 - (b^2)^3 \). This allows us to apply the difference of cubes formula.

**Hint:** Remember that \( x^3 - y^3 = (x - y)(x^2 + xy + y^2) \).

### Step 2: Apply the difference of cubes formula
