Using differentials, find the approximate value of `(255)^(1//4)`

Explanation

To find the approximate value of \( (255)^{1/4} \) using differentials, we can follow these steps:

### Step 1: Choose a value of \( x \)
We choose \( x = 256 \) because it is a perfect fourth power, and we know \( 256^{1/4} = 4 \).

### Step 2: Define the function
Let \( y = x^{1/4} \).
