3^{-5x+2}=(1/9)^{x+2}

Lösung

3^{- 5 x + 2} = (\frac{1}{9})^{x + 2}

x = 2

Schritte zur Lösung

3^{- 5 x + 2} = (\frac{1}{9})^{x + 2}

Wende Exponentenregel an

- 5 x + 2 = - 2 (x + 2)

Löse

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

x = 2

2 + x = 2^{x}

8 \cdot 2^{3 x} - 32 = 0

7^{x} = 349

3^{y} = 81

3^{2 x - 1} = 93
