The equation provided is:

\[
y = \left( \sqrt{t} \right)^t = t^{t/2}
\]

We are tasked with finding the derivative of \(y\) with respect to \(t\) using **logarithmic differentiation**.

### Steps for Logarithmic Differentiation:

1. Take the natural logarithm of both sides:
   \[
   \ln(y) = \ln\left(t^{t/2}\right)
   \]

2. Apply the logarithmic property \(\ln(a^b) = b \ln(a)\):
   \[
   \ln(y) = \frac{t}{2} \ln(t)
   \]

3. Differentiate both sides with respect to \(t\). Remember that \(\frac{d}{dt}[\ln(y)] = \frac{1}{y} \frac{dy}{dt}\) by implicit differentiation:
   \[
   \frac{1}{y} \frac{dy}{dt} = \frac{d}{dt}\left(\frac{t}{2} \ln(t)\right)
   \]

4. Use the product rule to differentiate the right-hand side. The product rule states \(\frac{d}{dt}[u v] = u'v + uv'\), where \(u = \frac{t}{2}\) and \(v = \ln(t)\):
   \[
   \frac{dy}{dt} = y \cdot \left[\frac{1}{2} \ln(t) + \frac{t}{2} \cdot \frac{1}{t}\right]
   \]

   Simplifying:
   \[
   \frac{dy}{dt} = y \left(\frac{1}{2} \ln(t) + \frac{1}{2}\right)
   \]

5. Substitute \(y = t^{t/2}\) back into the equation:
   \[
   \frac{dy}{dt} = t^{t/2} \left(\frac{1}{2} \ln(t) + \frac{1}{2}\right)
   \]

Thus, the derivative of \(y\) with respect to \(t\) is:

\[
\frac{dy}{dt} = t^{t/2} \left(\frac{1}{2} \ln(t) + \frac{1}{2}\right)
\]
