Using First principal differentiate w.r.t 'x',`x^(2//3)`

Explanation

To differentiate the function \( f(x) = x^{2/3} \) using the first principle of derivatives, we will follow these steps:

### Step 1: Define the function
Let \( f(x) = x^{2/3} \).

### Step 2: Apply the first principle of derivatives
The first principle states that the derivative \( \frac{dy}{dx} \) is given by:
\[
