e^{-0.05x}=0.01

Lösung

e^{- 0.05 x} = 0.01

x = - \frac{ln ( 0.01 )}{0.05}

Dezimale

x = 92.10340 \dots

Schritte zur Lösung

e^{- 0.05 x} = 0.01

Wende Exponentenregel an

- 0.05 x = ln (0.01)

Löse

- 0.05 x = ln (0.01) : x = - \frac{ln ( 0.01 )}{0.05}

x = - \frac{ln ( 0.01 )}{0.05}

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

5^{3 x + 7} = 2 5^{x - 4}

9^{x} - 10 \cdot 3^{x} + 9 = 0

so l v e f or t, A = P (1 + r)^{t}

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