Let's simplify the given expression step by step:

[tex]\[ \frac{\left(x^0 y^{\frac{2}{3}} z^{-2}\right)^{\frac{3}{2}}}{\left(x^2 z^{\frac{1}{2}}\right)^{-6}} \][/tex]

### Step 1: Simplify the numerator [tex]\(\left(x^0 y^{\frac{2}{3}} z^{-2}\right)^{\frac{3}{2}}\)[/tex]

First, recognize that [tex]\(x^0 = 1\)[/tex], which simplifies our numerator:

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

Now, we'll apply the exponent [tex]\(\frac{3}{2}\)[/tex] to both [tex]\(y^{\frac{2}{3}}\)[/tex] and [tex]\(z^{-2}\)[/tex]:

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

Next, multiply the exponents using [tex]\((a^m)^n = a^{m \cdot n}\)[/tex]:

[tex]\[ y^{\frac{2}{3} \cdot \frac{3}{2}} \cdot z^{-2 \cdot \frac{3}{2}} = y^1 \cdot z^{-3} \][/tex]

So, the numerator simplifies to:

[tex]\[ y^1 \cdot z^{-3} = y \cdot z^{-3} \][/tex]

### Step 2: Simplify the denominator [tex]\(\left(x^2 z^{\frac{1}{2}}\right)^{-6}\)[/tex]

Apply the exponent [tex]\(-6\)[/tex] to both [tex]\(x^2\)[/tex] and [tex]\(z^{\frac{1}{2}}\)[/tex]:

[tex]\[ \left(x^2\right)^{-6} \cdot \left(z^{\frac{1}{2}}\right)^{-6} \][/tex]

Again, multiply the exponents:

[tex]\[ x^{2 \cdot (-6)} \cdot z^{\frac{1}{2} \cdot (-6)} = x^{-12} \cdot z^{-3} \][/tex]

So, the denominator simplifies to:

[tex]\[ x^{-12} \cdot z^{-3} \][/tex]

### Step 3: Combine the simplified numerator and denominator

The simplified expression is then:

[tex]\[ \frac{y \cdot z^{-3}}{x^{-12} \cdot z^{-3}} \][/tex]

You can cancel out [tex]\(z^{-3}\)[/tex] in the numerator and the denominator:

[tex]\[ \frac{y}{x^{-12}} \][/tex]

Since dividing by [tex]\(x^{-12}\)[/tex] is equivalent to multiplying by [tex]\(x^{12}\)[/tex], the final expression becomes:

[tex]\[ y \cdot x^{12} \][/tex]

Thus, the simplified form of the given expression is:

[tex]\[ \boxed{yx^{12}} \][/tex]
