solvefor t,0.2=e^{-kt}

Lösung

löse nach

t, 0.2 = e^{- k t}

t = - \frac{ln ( 0.2 )}{k}

Schritte zur Lösung

0.2 = e^{- k t}

Wende Exponentenregel an

ln (0.2) = - k t

Löse

ln (0.2) = - k t : t = - \frac{ln ( 0.2 )}{k}

t = - \frac{ln ( 0.2 )}{k}

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

2^{x - 10} = x^{3}

e^{4 k} = \frac{3204}{2650}

3 3^{X} = 2

8^{x} = 2 + 7
