ln(e^{x+3})=10

Lösung

ln (e^{x + 3}) = 10

x = 7

Schritte zur Lösung

ln (e^{x + 3}) = 10

Wende Exponentenregel an

x + 3 = 10

Löse

x + 3 = 10 : x = 7

x = 7

3^{x} = \frac{1}{81}

3^{2 x} - 3^{x} - 72 = 0

e^{- 2 k} = 0

2^{3 x} \cdot 7^{x - 1} = 4^{x + 1}

so l v e f or x, (\frac{a}{b})^{x} - 1 = (\frac{b}{a})^{n} - 3
