medal to whoever solves this
let's simplify \[2\sqrt{27} = 2*(\sqrt{9}*\sqrt{3}) = 2*(3\sqrt{3}) = 6\sqrt{3}\] so it becomes \[3\sqrt{3}-4\sqrt{3}+6\sqrt{3}\] You would then apply order of operations addition first followed by subtraction.

So what is the answer @Photon336 ?
yeah, we can't just give out direct answers. first pretend that the radical's arent there/ so we would have 3-4+6 after you figure that out put the radical three next to the result.
