To find the derivative of the given function \( y(t) = \frac{(t^4 + \sqrt{3})(\sqrt{t} - 1)}{t^2} \) at \( t = 2 \), we will first use the quotient rule to differentiate it. The quotient rule is given by:

\[
\left(\frac{u}{v}\right)' = \frac{u'v - uv'}{v^2}
\]

where \( u = (t^4 + \sqrt{3})(\sqrt{t} - 1) \) and \( v = t^2 \).

### Step 1: Differentiate \( u \) and \( v \)

1. **Differentiate \( v = t^2 \):**
   \[
   v' = 2t
   \]

2. **Differentiate \( u = (t^4 + \sqrt{3})(\sqrt{t} - 1) \):**
   Let's use the product rule, where \( u_1 = t^4 + \sqrt{3} \) and \( u_2 = \sqrt{t} - 1 \).

   \[
   u_1' = 4t^3
   \]
   \[
   u_2' = \frac{1}{2\sqrt{t}}
   \]

   Now, applying the product rule \( (u_1 u_2)' = u_1' u_2 + u_1 u_2' \):

   \[
   u' = 4t^3 (\sqrt{t} - 1) + (t^4 + \sqrt{3}) \frac{1}{2\sqrt{t}}
   \]

### Step 2: Apply the Quotient Rule

\[
y'(t) = \frac{u' \cdot v - u \cdot v'}{v^2}
\]

\[
y'(t) = \frac{\left[4t^3 (\sqrt{t} - 1) + \frac{t^4 + \sqrt{3}}{2\sqrt{t}}\right] t^2 - (t^4 + \sqrt{3})(\sqrt{t} - 1) \cdot 2t}{t^4}
\]

### Step 3: Simplify and Evaluate at \( t = 2 \)

1. Simplify the expression for \( y'(t) \).
2. Substitute \( t = 2 \) into the simplified expression to find \( y'(2) \).
