Simplify the following expression.

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



Answer :

Sure! Let's simplify the given expression step-by-step.

Given expression:

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

### Step 1: Simplify the Numerator
Start with the numerator:

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

The properties of exponents tell us that we can distribute the [tex]\(\frac{3}{2}\)[/tex] exponent to each factor inside the parenthesis:

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

Simplify each term separately:

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

So the numerator simplifies to:

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

### Step 2: Simplify the Denominator
Now, let's consider the denominator:

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

Raising any expression to the power of zero results in 1 (as long as the base isn't zero):

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

### Step 3: Combine the Result
Now we have:

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

Which simplifies to just:

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

To write it in a single expression:

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

Thus, the simplified form of the original expression is:

[tex]\[ \boxed{\frac{y}{z^3}} \][/tex]

This is the final simplified expression.
