Question

Simplify the following expression by adding and subtracting: 3√3 - 4√3 + 2√27
A. 5√3
B. 7√3
C. 10√3
D. 17√3

Answer 1

medal to whoever solves this

Answer 2

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.

Answer 4

So what is the answer @Photon336 ?

Answer 5

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.
