Wait is it,
$$\sqrt[3]{4n}$$ or $$3\sqrt{4n}$$

goose. · Answer

Going to assume it is the first one,

anonymous · Answer

Yeah, the first one.

goose. · Answer

Well then I'm stumped, if you already tried C and D. as the answer should be C.

anonymous · Answer

That's what I thought but it was wrong so I tried D and it was wrong too.

anonymous · Answer

the answer is D

anonymous · Answer

Square root of 2 can also be written as (2)^1/2
Cube root or third root of any number n is (n)^1/3
So what will the third root of any number 4n be? :)

anonymous · Answer

Nope. It was C, thanks anways though.

anonymous · Answer

I guess I thought it said it was wrong and it was actually right.

anonymous · Answer

SRryy I was meant to say C I forgot about brackets

anonymous · Answer

It's all good.
