Answer:

Explanation:

hello, you know that


\sqrt[5]{x^5}=x

so, I can write


\sqrt[5]{2^5}=\sqrt[5]{32}=2\\\\\sqrt[5]{3^5}=\sqrt[5]{243}=3\\\\\sqrt[5]{4^5}=\sqrt[5]{1024}=4\\\\\sqrt[5]{5^5}=\sqrt[5]{3125}=5

So, the winners are 32, 243, 1024, 3125 !!

You know that
i^2=-1, right?


√(-9)=√((3i)^2)=3i

So, the answer is 3i

Thank you
