Differentiate with respect to x,`(x+1/x)^(3)`

Explanation

To differentiate the function \( y = \left( x + \frac{1}{x} \right)^3 \) with respect to \( x \), we will use the chain rule and the power rule of differentiation. Let's go through the steps:

### Step-by-step Solution:

1. **Identify the function**:
We have \( y = \left( x + \frac{1}{x} \right)^3 \).

2. **Apply the chain rule**:
