<reasoning>
Apply the product property of radicals
Using the Product Property of Radicals knowledge point
\[
\sqrt{30} \cdot \sqrt{10} = \sqrt{30 \cdot 10} = \sqrt{300}
\]
Simplify the radical expression
Using the Radical Simplification knowledge point
\[
\sqrt{300} = \sqrt{100 \cdot 3} = \sqrt{10^2 \cdot 3} = 10\sqrt{3}
\]
</reasoning>
