To simplify the given expression, we can use the property of radicals that states \(\sqrt[n]{a} / \sqrt[n]{b} = \sqrt[n]{a/b}\). This allows us to combine the radicals into a single radical expression. Then, we can simplify the expression inside the radical.
Step 1: Combine the Radicals
We start by using the property of radicals:
\[
\frac{3 \sqrt[4]{80}}{\sqrt[4]{5}} = 3 \cdot \frac{\sqrt[4]{80}}{\sqrt[4]{5}} = 3 \cdot \sqrt[4]{\frac{80}{5}}
\]
Step 2: Simplify the Fraction Inside the Radical
Next, we simplify the fraction inside the radical:
\[
\frac{80}{5} = 16
\]
So the expression becomes:
\[
3 \cdot \sqrt[4]{16}
\]
Step 3: Simplify the Fourth Root
We know that:
\[
\sqrt[4]{16} = 2
\]
Thus, the expression simplifies to:
\[
3 \cdot 2 = 6
\]
