Schritte zur Lösung

(\frac{16}{25})^{- \frac{1}{2}}

Wende Exponentenregel an:

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

(\frac{16}{25})^{- \frac{1}{2}} = \frac{1}{( \frac{16}{25} ) ^{\frac{1}{2}}}

= \frac{1}{( \frac{16}{25} ) ^{\frac{1}{2}}}

(\frac{16}{25})^{\frac{1}{2}} = \frac{4}{5}

= \frac{1}{\frac{4}{5}}

Wende Bruchregel an:

\frac{1}{\frac{b}{c}} = \frac{c}{b}

= \frac{5}{4}

8 = - 8 w + 4 (w - 4)

6 u^{2} - 30 u = 0

5 v = v + 32

0 = x^{2} + 4 x - 5

12 - 2 x = 8 x - 18
