Lösung

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

x = - \frac{5}{2}

Dezimale

x = - 2.5

Schritte zur Lösung

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

Wende Exponentenregel an

- 2 (x + 2) = 1

Löse

- 2 (x + 2) = 1 : x = - \frac{5}{2}

x = - \frac{5}{2}

3^{5 x - 4} = 6

5^{5 x + 7} = 12 5^{x + 3}

\frac{62 5 ^{c - 3}}{125} = 5^{4}

100 = 1 0^{x}

3^{x} = - 27
