Ответ:
[tex]10^{-1}+5^{-2}=\\\frac{1}{10^1} +\frac{1}{5^2} =\\\frac{1}{10} +\frac{1}{25} =\\\frac{5}{50} +\frac{2}{50} =\\\frac{7}{50}[/tex]
Объяснение:
формула [tex]a^{-n}=\frac{1}{a^n}[/tex]
[tex]\displaystyle\bf\\10^{-1} +5^{-2} =\frac{1}{10} +\frac{1}{5^{2} } =\frac{1}{10} +\frac{1}{25} =0,1+0,04=0,14[/tex]
