Schritte zur Lösung

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

Wende Exponentenregel an

(x - 2) ln (3) = (x + 1) ln (5)

Löse

(x - 2) ln (3) = (x + 1) ln (5) : x = \frac{ln ( 45 )}{ln ( 3 ) - ln ( 5 )}

x = \frac{ln ( 45 )}{ln ( 3 ) - ln ( 5 )}

e^{- x} = 2

6 4^{7 x - 8} = 1

e^{- x^{2}} - 2 e^{- x^{2}} x^{2} = 0

e^{- 6 x} = 0.15

x^{l n (x)} = e^{(l n (x))^{3}}
