Lösung

3 2^{- 2 k} = 64

k = - \frac{3}{5}

Dezimale

k = - 0.6

Schritte zur Lösung

3 2^{- 2 k} = 64

Wende Exponentenregel an

- 10 k = 6

Löse

- 10 k = 6 : k = - \frac{3}{5}

k = - \frac{3}{5}

so l v e f or j, z = e^{- \frac{π}{4} j}

3^{x} + 3^{- x} = 5

ln (e^{x} - 3 e^{- x}) = ln (2)

4^{x + 1} = 2^{x - 1}

3^{2 x - 1} = 7^{x}
