Schritte zur Lösung

2^{x} = 1.5

Wende Exponentenregel an

x ln (2) = ln (1.5)

Löse

x ln (2) = ln (1.5) : x = \frac{ln ( 1.5 )}{ln ( 2 )}

x = \frac{ln ( 1.5 )}{ln ( 2 )}

4^{x} - 2^{x} - 12 = 0

2 7^{5 x - 4} = 8 1^{7 x - 2}

6 1^{\frac{1}{3}} = k 61

5^{x - 1} = 2 + \frac{3}{5 ^{x - 2}}

e^{3 x} - e^{2 (3 x)} = 0
