Question

0,1x √200 +2. √0,08 +0,4. √50

 

Answer 1

\(0,1.\sqrt{200}+2.\sqrt{0,08}+0,4.\sqrt{50}\)

\(=0,1.10\sqrt{2}+2.\frac{\sqrt{2}}{5}+0,4.5\sqrt{2}\)

\(=1.\sqrt{2}+\frac{2\sqrt{2}}{5}+2\sqrt{2}\)

\(=\sqrt{2}+\frac{2\sqrt{2}}{5}+2\sqrt{2}\)

\(=\sqrt{2}\left(1+\frac{2}{5}+2\right)\)

\(=\sqrt{2}.\frac{17}{5}=\frac{17\sqrt{2}}{5}\)

Answer 2

0,1x √200 +2. √0,08 +0,4. √50 = \(4,808326112=\frac{17\sqrt{2}}{5}\)
