Simplify. Express your answer in simplified radical form
(2 times the square root of 12) + (4 times the square root of 27)
(2 times 3.464)+(4 times 5.196)
6.928 + 20.784
27.712

That is one way you could solve it. Another way to simplify without having to use a decimal is
(2*sqrt(4*3)) + (4*sqrt(9*3))
(2*2sqrt3) + (4*3sqrt3)
(4sqrt3) + (12sqrt3)
sqrt3(4 + 12)
sqrt3(16)
16sqrt3

(2â12) + (4â27) =
(2â(4*3)) + (4â(9*3)) =
(2*2â3) + (4*3â3) =
(4â3) + (12â3) =
16â3
which is the form requested.

Well, it says simplified radical form, so that would imply that the answer would contain a radical. So to answer your question, no that is not correct.
