12. Beчислите 9+\documentclass{article} \usepackage{amsmath} \begin{document} $$\sqrt{\frac{1}{16}}$$ \end{document}+1\documentclass{article} \usepackage{amsmath} \begin{document} $$\sqrt{\frac{24}{25}}$$ \end{document}

12. Вычислим значение выражения 9+\documentclass{article} \usepackage{amsmath} \begin{document} $$\sqrt{\frac{1}{16}}$$ \end{document}+1\documentclass{article} \usepackage{amsmath} \begin{document} $$\sqrt{\frac{24}{25}}$$ \end{document}.

$$\sqrt{\frac{1}{16}}$$ = \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{1}{4}$$ \end{document} = 0,25

$$\sqrt{\frac{24}{25}}$$ = \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{\sqrt{24}}{5}$$ \end{document} = \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{2\sqrt{6}}{5}$$ \end{document}

9 + 0,25 + 1 ∙ \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{2\sqrt{6}}{5}$$ \end{document} = 9,25 + \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{2\sqrt{6}}{5}$$ \end{document}

Ответ: 9,25 + \documentclass{article} \usepackage{amsmath} \begin{document} $$\frac{2\sqrt{6}}{5}$$ \end{document}
