3^{2n-1}= 1/81

Lösung

3^{2 n - 1} = \frac{1}{81}

n = - \frac{3}{2}

Dezimale

n = - 1.5

Schritte zur Lösung

3^{2 n - 1} = \frac{1}{81}

Wende Exponentenregel an

2 n - 1 = - 4

Löse

2 n - 1 = - 4 : n = - \frac{3}{2}

n = - \frac{3}{2}

3^{x + 1} + 3^{x + 2} + 3^{x - 1} = 999

so l v e f or t, y = e^{3 t}

2^{3 n + 1} = 64

- 2 = 4^{x}

2^{24 x + 12} = 1 6^{6 x + 3}
