3^{x+7}=9^{x+1}

Lösung

3^{x + 7} = 9^{x + 1}

x = 5

Schritte zur Lösung

3^{x + 7} = 9^{x + 1}

Wende Exponentenregel an

x + 7 = 2 (x + 1)

Löse

x + 7 = 2 (x + 1) : x = 5

x = 5

so l v e f or x, 3^{x} + 2^{y} = 1 + 2^{z}

e^{x} \cdot (1 + e^{x}) = \frac{3}{4}

2187 = 2^{x}

1. 5^{x} = 10

1 6^{x} + 2 0^{x} - 2 5^{x} = 0
