Schritte zur Lösung

(\frac{1}{27})^{- \frac{2}{3}}

Wende Exponentenregel an:

a^{- b} = \frac{1}{a ^{b}}

(\frac{1}{27})^{- \frac{2}{3}} = \frac{1}{( \frac{1}{27} ) ^{\frac{2}{3}}}

= \frac{1}{( \frac{1}{27} ) ^{\frac{2}{3}}}

(\frac{1}{27})^{\frac{2}{3}} = \frac{1}{9}

= \frac{1}{\frac{1}{9}}

\frac{1}{\frac{1}{9}} = 9

= 9
