To simplify the expression:

\[
\frac{x^{3/4}}{x^{5/4} \cdot x^{-2}}
\]

### Step 1: Combine the terms in the denominator
The denominator consists of \(x^{5/4} \cdot x^{-2}\). To simplify this, we apply the rule of exponents:

\[
x^{a} \cdot x^{b} = x^{a+b}
\]

Thus:

\[
x^{5/4} \cdot x^{-2} = x^{5/4 - 2} = x^{5/4 - 8/4} = x^{-3/4}
\]

### Step 2: Apply the rule of division for exponents
Now the expression becomes:

\[
\frac{x^{3/4}}{x^{-3/4}}
\]

When dividing terms with the same base, subtract the exponents:

\[
x^{3/4 - (-3/4)} = x^{3/4 + 3/4} = x^{6/4} = x^{3/2}
\]

### Final Answer:
\[
x^{3/2}
\]
