Absolutely! Let's consider a simple example involving the subtraction of radicals.

Let's subtract the following radicals:

\[
\sqrt{45} - \sqrt{20}
\]

**Step 1: Simplify the radicals.**

First, we can simplify \(\sqrt{45}\) and \(\sqrt{20}\):

\[
\sqrt{45} = \sqrt{9 \cdot 5} = \sqrt{9} \cdot \sqrt{5} = 3\sqrt{5}
\]

\[
\sqrt{20} = \sqrt{4 \cdot 5} = \sqrt{4} \cdot \sqrt{5} = 2\sqrt{5}
\]

**Step 2: Perform the subtraction.**

Now we can substitute these simplified forms back into the expression:

\[
3\sqrt{5} - 2\sqrt{5}
\]

Since both terms have a common radical (\(\sqrt{5}\)), we can combine them:

\[
(3 - 2)\sqrt{5} = 1\sqrt{5} = \sqrt{5}
\]

So the result of the expression \(\sqrt{45} - \sqrt{20}\) is:

\[
\sqrt{5}
\]
