Before you say anything, yes I did try. I still can't do it. My answers never seem to look correct. I only tried the first one.

What I got for the first one so far: \(6\sqrt[4]{3^4x^4}\)

\(6\sqrt[4]{567x^4} = \\ 6\sqrt[4]{3^4x^4\cdot 7} =\\ 6\cdot 3x\sqrt[4]{7} = \\ 18x\sqrt[4]{7}\)

 

\(4\sqrt[3]{64n^8} = \\ 4\sqrt[3]{2^6 n^6 \cdot n^2} = \\ 4\cdot 2^2 n^2 \sqrt[3]{n^2} = \\ 16n^2 \sqrt[3]{n^2}\)

Seems I would've done it the wrong way anyways, why is it that I have to multiply by 7?

\(567 = 81 \cdot 7 = 3^4 \cdot 7\)

It is very nice to see you interacting Panda but it would be nice to also see you say 'thanks' to Rom :)
