Question

giúp mình rút gọn bài này với

\(\sqrt{150}+\sqrt{1,6}.\sqrt{60}+4,5\sqrt{\frac{4}{3}}-\sqrt{6}\)

Answer 1

\(=\sqrt{2.5^2.3}+\sqrt{0.4^2}.\sqrt{2^2.3.5}+4,5.\frac{2}{\sqrt{3}}-\sqrt{2.3}.\)

\(=\sqrt{2.5^2.3^2}+\frac{2}{3}.\sqrt{2^2.3^2.5}+9-\sqrt{2.3}\)

\(=3.5.3.\sqrt{2}+2.2.3.\sqrt{5}+9-3.\sqrt{2.3}\)

\(=45\sqrt{2}+12\sqrt{5}+9-3\sqrt{6}\)
