Question

I need help with these 2 problems

Answer 1

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
