Schritte zur Lösung

3^{x} = \frac{14}{25}

Wende Exponentenregel an

x ln (3) = ln (\frac{14}{25})

Löse

x ln (3) = ln (\frac{14}{25}) : x = \frac{ln ( \frac{14}{25} )}{ln ( 3 )}

x = \frac{ln ( \frac{14}{25} )}{ln ( 3 )}

3^{3 x + 1} = 9^{x + 4}

5^{5 - x} = 2^{5 - x}

5^{3 x - 1} = 3^{1 - 2 x}

3^{2 x - 1} - 3^{x} = 18

2^{x} - 3 = 8
