11. Вычислите 6-+\documentclass{article} \usepackage{amsmath} \begin{document} $$\sqrt{\frac{1}{4}}$$ \end{document} +3\documentclass{article} \usepackage{amsmath} \begin{document} $$\sqrt{\frac{6}{25}}$$ \end{document}

11. Вычислим значение выражения 6-\documentclass{article} \usepackage{amsmath} \begin{document} $$\sqrt{\frac{1}{4}}$$ \end{document} +3\documentclass{article} \usepackage{amsmath} \begin{document} $$\sqrt{\frac{6}{25}}$$ \end{document}.

$$\sqrt{\frac{1}{4}}$$ = \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{1}{2}$$ \end{document} = 0,5

$$\sqrt{\frac{6}{25}}$$ = \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{\sqrt{6}}{5}$$ \end{document}

6 - 0,5 + 3 ∙ \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{\sqrt{6}}{5}$$ \end{document} = 5,5 + \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{3\sqrt{6}}{5}$$ \end{document}

Ответ: 5,5 + \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{3\sqrt{6}}{5}$$ \end{document}
