4^x=(1/8)^{x+5}

Lösung

4^{x} = (\frac{1}{8})^{x + 5}

x = - 3

Schritte zur Lösung

4^{x} = (\frac{1}{8})^{x + 5}

Wende Exponentenregel an

2 x = - 3 (x + 5)

Löse

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

x = - 3

2^{3 - 8 w} - 7 = 11

1 = 4^{x}

4^{x + 2} = 12

5^{9 x + 5} = 2

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