thực hiện phép tính

\(\sqrt{12}+2\sqrt{27}+3\sqrt{75}-9\sqrt{48}\)

Answer 1

[Phùng Khánh Linh]

\(\sqrt{12}+2\sqrt{27}+3\sqrt{75}-9\sqrt{48}=2\sqrt{3}+6\sqrt{3}+15\sqrt{3}-36\sqrt{3}=-13\sqrt{3}\)

Answer 2

[nguyễn hồng hạnh]

\(\sqrt{12}+2\sqrt{27}+3\sqrt{75}-9\sqrt{48}\)

\(=\sqrt{3.4}+2\sqrt{3.9}+3\sqrt{5.5.3}-9\sqrt{4.4.3}\)

\(=2\sqrt{3}+2.3\sqrt{3}+15\sqrt{3}-36\sqrt{3}\)

\(=-13\sqrt{3}\)
