\(M=\frac{1}{4}\sqrt{32}-2\sqrt{50}+\frac{\sqrt{22}}{\sqrt{11}}\)
\(M=\frac{1}{4}\sqrt{16\times2}-2\sqrt{25\times2}+\sqrt{\frac{22}{11}}\)
\(M=\frac{1}{4}\times4\times\sqrt{2}-2\times5\times\sqrt{2}+\sqrt{2}\)
\(M=\sqrt{2}-10\sqrt{2}+\sqrt{2}\)
\(M=-8\sqrt{2}\)
M=\(\frac{1}{4}\)\(\sqrt{32}\)-2\(\sqrt{50}\)+\(\frac{\sqrt{22}}{\sqrt{11}}\)
M=\(\frac{1}{4}\)\(\sqrt{16.2}\)-2\(\sqrt{25.2}\)+\(\sqrt{\frac{22}{11}}\)
M=\(\frac{1}{4}\).4.\(\sqrt{2}\)-2.5.\(\sqrt{2}\)+\(\sqrt{2}\)
M=\(\sqrt{2}\)-10\(\sqrt{2}\)+\(\sqrt{2}\)
M=-10\(\sqrt{2}\)
