Dezimale

x = - 0.5

Schritte zur Lösung

(3^{x})^{8} = \frac{1}{81}

Wende Exponentenregel an

x \cdot 8 = - 4

Löse

x \cdot 8 = - 4 : x = - \frac{1}{2}

x = - \frac{1}{2}

3^{2 z - 1} = 243

3 + 4 e^{x} + 1 = 11

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

2^{x} \cdot 5^{x - 1} = 0.01

2^{x + 2} + 2^{x - 1} - 2^{x - 3} = 70
