e^{(-0.25)x}=0.98

Lösung

e^{(- 0.25) x} = 0.98

x = - \frac{ln ( 0.98 )}{0.25}

Dezimale

x = 0.08081 \dots

Schritte zur Lösung

e^{(- 0.25) x} = 0.98

Wende Exponentenregel an

(- 0.25) x = ln (0.98)

Löse

(- 0.25) x = ln (0.98) : x = - \frac{ln ( 0.98 )}{0.25}

x = - \frac{ln ( 0.98 )}{0.25}

e^{2 l n (3)} = 3^{1 - 2 x}

2 = e^{4 k}

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

1 6^{5 - x} = 8^{2 x + 4}

256 = 2^{n - 1}
