e^{-x}= 1/2

Lösung

e^{- x} = \frac{1}{2}

x = ln (2)

Dezimale

x = 0.69314 \dots

Schritte zur Lösung

e^{- x} = \frac{1}{2}

Wende Exponentenregel an

- x = ln (\frac{1}{2})

Löse

- x = ln (\frac{1}{2}) : x = ln (2)

x = ln (2)

e^{6 x} + 10 e^{3 x} - 11 = 0

(\frac{1}{3})^{x} = 27

so l v e f or x, 2^{x} = 2^{y}

9^{5 x} = 1024

so l v e f or y, x = e^{- y}
