Schritte zur Lösung

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

Wende Exponentenregel an:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

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

= - 2 \cdot \frac{2 ^{2}}{3 ^{2}}

2^{2} = 4

= - 2 \cdot \frac{4}{3 ^{2}}

3^{2} = 9

= - 2 \cdot \frac{4}{9}

- 2 \cdot \frac{4}{9} = - \frac{8}{9}

= - \frac{8}{9}

x^{2} + 16 x = - 139

- 2 x + 6 = 24

4 x^{1} < - 11

x^{2} + x - 31 = 0

- 3 + 2 x > 9
