3^{-(x-2)}= 1/27

Lösung

3^{- (x - 2)} = \frac{1}{27}

x = 5

Schritte zur Lösung

3^{- (x - 2)} = \frac{1}{27}

Wende Exponentenregel an

- (x - 2) = - 3

Löse

- (x - 2) = - 3 : x = 5

x = 5

3^{2 x} = 5

\frac{e ^{x} - 3 e ^{- x}}{2} = 1

2^{x} = \frac{1}{128}

e^{x - 1} - 6 = - 2 x - 3

3^{x + 1} = 5
