(1/81)^{3x-5}=243

Lösung

(\frac{1}{81})^{3 x - 5} = 243

x = \frac{5}{4}

Dezimale

x = 1.25

Schritte zur Lösung

(\frac{1}{81})^{3 x - 5} = 243

Wende Exponentenregel an

- 4 (3 x - 5) = 5

Löse

- 4 (3 x - 5) = 5 : x = \frac{5}{4}

x = \frac{5}{4}

9^{2 x} = 81

m = 0.9 e^{- 0.06 t}

3^{x - 5} = 2

so l v e f or x, ln (y) = e^{x} + c

\frac{1}{25} = 5^{x}
