Schritte zur Lösung

1 3^{2 x} = 4

Wende Exponentenregel an

2 x ln (13) = ln (4)

Löse

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

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

3^{2 x} = 10 (3^{x}) - 9

100 e^{- 0.6 x} = 20

so l v e f or x, 2^{3 x - 1} = 5^{x - 2}

0.2 = 0.9 9^{x}

25 (10)^{2 t} = 208
