1/5 =5^{2c+3}

Lösung

\frac{1}{5} = 5^{2 c + 3}

c = - 2

Schritte zur Lösung

\frac{1}{5} = 5^{2 c + 3}

Wende Exponentenregel an

- 1 = 2 c + 3

Löse

- 1 = 2 c + 3 : c = - 2

c = - 2

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

6^{2 x} - 42 (6^{x}) + 216 = 0

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

10 = 0.1 7^{- x}

2^{x - 2} = 5
