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 ?

photon336 · Answer

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.
