To add the radicals \( \sqrt{22} + \sqrt{22} + \sqrt{22} \), we can treat each term as a like term.
So:
\[
\sqrt{22} + \sqrt{22} + \sqrt{22} = 3\sqrt{22}
\]
Based on the options provided, none of them exactly match the \( 3\sqrt{22} \) we calculated, but here's a breakdown of the options you posted:
1. \( 5\sqrt{22} \)
2. \( 5\sqrt{66} \)
3. \( \sqrt[3]{22} + 4\sqrt{22} \)
4. \( \sqrt[3]{22} + 4\sqrt{4} \)
If these choices are representing an addition of three \( \sqrt{22} \) terms, option 3 would be the closest choice for understanding what to do with \( \sqrt{22} \) but doesn't represent the total correctly.
Thus, the answer to the question is simply:
\[
3\sqrt{22}
\]
If choosing an answer is required based on your listed options and depending on what it means (if it asks to recalculate or similar), option 3 might be a misrepresentation contextually or simply needs clarification.
