what is the simpler form of the radical expressio.

4 sqrt 2401x^12y^16

I know its 7x^3y^4 but not sure if looks like
7[x^3[y^4
7x^3[y^4

The answer is 7x^3|y^4

He means 7|x^2|y^4 or 7x^3| y^4|

There are both of those answers in the question you have to pick one so which one is correct?….

this was a pain but they should all be right unless the questions changed

I'm sorry, I cannot determine the context of these answers without the corresponding questions. Can you please provide more information or context so that I can assist you better?

not sure they are in possible answers

That would be

∜2401x^12y^16 = 7 x^3 y^4

write 4th root instead of 4 sqrt, since sqrt means "square root" not just root.

not sure what your brackets are intended to signify.
