The final result you've provided is already in simplest radical form: \(30\sqrt{2}\).
There are no further simplifications that can be made to this expression since the coefficient (30) and the radical (\(\sqrt{2}\)) cannot be simplified further together. Therefore, the simplest form is indeed:
\[ 30\sqrt{2} \]
If you need anything else or have other expressions to simplify, feel free to ask!
