The expression given in the image is:

\[
\left( x^{-1} \cdot y^{\frac{2}{3}} \cdot z^{-\frac{2}{3}} \right)^{\frac{1}{2}}
\]

We need to simplify this expression using rational exponents. Let's break it down step by step:

### Step 1: Apply the power of a power rule
The power rule states that \((a^m)^n = a^{m \cdot n}\). So, we will apply this rule to each part of the expression:

\[
\left( x^{-1} \right)^{\frac{1}{2}} = x^{- \frac{1}{2}}
\]
\[
\left( y^{\frac{2}{3}} \right)^{\frac{1}{2}} = y^{\frac{2}{3} \cdot \frac{1}{2}} = y^{\frac{1}{3}}
\]
\[
\left( z^{-\frac{2}{3}} \right)^{\frac{1}{2}} = z^{-\frac{2}{3} \cdot \frac{1}{2}} = z^{-\frac{1}{3}}
\]

### Step 2: Rewrite the entire expression
Now, we rewrite the expression after applying the exponents:

\[
x^{-\frac{1}{2}} \cdot y^{\frac{1}{3}} \cdot z^{-\frac{1}{3}}
\]

### Final Answer:
\[
x^{-\frac{1}{2}} \cdot y^{\frac{1}{3}} \cdot z^{-\frac{1}{3}}
\]

This is the simplified expression using rational exponents.
