Lösung

4^{x^{2} - 72} = 1 6^{3 x}

x = 12, x = - 6

Schritte zur Lösung

4^{x^{2} - 72} = 1 6^{3 x}

Wende Exponentenregel an

x^{2} - 72 = 6 x

Löse

x^{2} - 72 = 6 x : x = 12, x = - 6

x = 12, x = - 6

25 \cdot 3^{0.3 x} = 250

(e^{x} - 1) (e^{x} + 1) = 0

e^{x} = 42

25 \cdot 1.00 5^{t} = 31

5^{2 x - 1} = 1
