Schritte zur Lösung

0. 8^{x} = 0.05

Wende Exponentenregel an

x ln (0.8) = ln (0.05)

Löse

x ln (0.8) = ln (0.05) : x = \frac{ln ( 0.05 )}{ln ( 0.8 )}

x = \frac{ln ( 0.05 )}{ln ( 0.8 )}

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

e^{2 x - 3} = 75

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

3 \cdot 2^{x + 2} - 5 \cdot 2^{x} = 56

e^{x + 1} = 3
