(\frac{1}{4})^{- \frac{1}{2}}

Wende Exponentenregel an:

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

(\frac{1}{4})^{- \frac{1}{2}} = \frac{1}{( \frac{1}{4} ) ^{\frac{1}{2}}}

= \frac{1}{( \frac{1}{4} ) ^{\frac{1}{2}}}

(\frac{1}{4})^{\frac{1}{2}} = \frac{1}{2}

= \frac{1}{\frac{1}{2}}

\frac{1}{\frac{1}{2}} = 2

= 2

x - \frac{3}{7} = \frac{4}{7}

4 = (y - 7)^{2}

- 1.8 x^{2} + 14.4 x = 0

∣ x ∣ - 5 \leq - 2

(x + 9)^{2} (x + 2) (x - 1) > 0
