Schritte zur Lösung

3^{2 x - 3} = 21

Wende Exponentenregel an

(2 x - 3) ln (3) = ln (21)

Löse

(2 x - 3) ln (3) = ln (21) : x = \frac{ln ( 567 )}{2 ln ( 3 )}

x = \frac{ln ( 567 )}{2 ln ( 3 )}

6^{9 x - 4} = 44

25 = 11 (1 + 0.14)^{x}

2 x e^{x} = 0

so l v e f or y, ln (2 x) + e^{y} = 1

3000 = 30 \cdot 50000 0^{x}
