Schritte zur Lösung

65 = 1 5^{x}

Wende Exponentenregel an

ln (65) = x ln (15)

Löse

ln (65) = x ln (15) : x = \frac{ln ( 65 )}{ln ( 15 )}

x = \frac{ln ( 65 )}{ln ( 15 )}

62 5^{x + 5} = 5^{3 x - 4} 2 5^{2 x - 3}

8 1^{x^{2} - 1} = 27

2^{3 x} = \frac{1}{16}

so l v e f or x, 2^{x} = 1

e^{x} - 9 x = 0
