Вычислите [latex] \frac{1}{5}* \sqrt{36}-0,2 \sqrt{625}+ \frac{7}{16} \sqrt{1 \frac{15}{49} } [/latex]

[latex] \frac{1}{5}\cdot \sqrt{36}-0,2\cdot \sqrt{625}+ \frac{7}{16}\cdot \sqrt{1 \frac{15}{49} }= \\ =\frac{1}{5}\cdot 6-0,2\cdot 25+ \frac{7}{16}\cdot \sqrt{ \frac{64}{49} }= \\ =\frac{1}{5}\cdot 6-0,2\cdot 25+ \frac{7}{16}\cdot \frac{8}{7} = \\ =1,2-5+0,5=-3,3 [/latex]
