e^{-8n-9}=36.5

Lösung

e^{- 8 n - 9} = 36.5

n = - \frac{ln ( 36.5 ) + 9}{8}

Dezimale

n = - 1.57466 \dots

Schritte zur Lösung

e^{- 8 n - 9} = 36.5

Wende Exponentenregel an

- 8 n - 9 = ln (36.5)

Löse

- 8 n - 9 = ln (36.5) : n = - \frac{ln ( 36.5 ) + 9}{8}

n = - \frac{ln ( 36.5 ) + 9}{8}

e^{- 2 t} + 6 = 5 e^{- t}

5^{x} = 40

ln^{2} (3) \cdot 3^{x} = 0

5^{x} = 49

so l v e f or x, 3 = 2^{x}
