Schritte zur Lösung

1 3^{x} = 4

Wende Exponentenregel an

x ln (13) = ln (4)

Löse

x ln (13) = ln (4) : x = \frac{2 ln ( 2 )}{ln ( 13 )}

x = \frac{2 ln ( 2 )}{ln ( 13 )}

3 \cdot 5^{x + 1} - 1 = 11

3^{2 x} - 3^{x + 2} + 8 = 0

e^{- 2 t} - 4 \cdot e^{- t} + 4 = 0

4^{- 3 v} = 64

2^{- 3 x} = 16
