Schritte zur Lösung

2^{x} = 20000

Wende Exponentenregel an

x ln (2) = ln (20000)

Löse

x ln (2) = ln (20000) : x = \frac{ln ( 20000 )}{ln ( 2 )}

x = \frac{ln ( 20000 )}{ln ( 2 )}

e^{x} x^{2} + 4 e^{x} x + 2 e^{x} = 0

3^{2 x} = 9^{\frac{5}{2} x - 3}

so l v e f or x, 8 1^{x} = 3

5^{x - 1} = 5^{7 - 3 x}

2^{x} = 200
