-3 < x < 0
x yerine gelebilecek sayılar:
=> - 2, - 1
[tex]\color{gold}\texttt{3}^{\color{gold}\texttt{-2 }} \color{gold}\texttt{ = } \frac{\color{gold}\texttt{1}}\color{gold}\texttt{3}^{\color{gold}\texttt{2}}[/tex]
[tex]\color{gold}\texttt{=} \frac{\color{gold}\texttt{1}}\color{gold}\texttt{9}[/tex]
[tex]\color{gold}\texttt{3}^{\color{gold}\texttt{-1 }} \color{gold}\texttt{ = } \frac{\color{gold}\texttt{1}}\color{gold}\texttt{3}^{\color{gold}\texttt{1}}[/tex]
[tex]\color{gold}\texttt{=} \frac{\color{gold}\texttt{1}}\color{gold}\texttt{3}[/tex]
Şimdi bu değerlerin toplamını bulacağız:
[tex]\frac{\color{gold}\texttt{1}}{\color{gold}\texttt{9}} \color{gold}\texttt{ + } \color{gold}\texttt{}\frac{\color{gold}\texttt{1}}{\color{gold}\texttt{3}} = \frac{\color{gold}\texttt{4}}{\color{gold}\texttt{9}} \: \\ \color{gold}\texttt{(3)} [/tex]
