2^x=(0.25)^{x-1}

Lösung

2^{x} = (0.25)^{x - 1}

x = \frac{2}{3}

Dezimale

x = 0.66666 \dots

Schritte zur Lösung

2^{x} = (0.25)^{x - 1}

2^{x} = (\frac{1}{4})^{x - 1}

Wende Exponentenregel an

x = - 2 (x - 1)

Löse

x = - 2 (x - 1) : x = \frac{2}{3}

x = \frac{2}{3}

4 + 6^{2 x + 3} = 14

10. 2^{x^{2} - 4} = 320

so l v e f or x, e^{2 x} - 5 e^{x} + 4 = 0

2^{x} = 500

ln (e^{3 x}) = 1
