Schritte zur Lösung

1 1^{x + 5} = 18

Wende Exponentenregel an

(x + 5) ln (11) = ln (18)

Löse

(x + 5) ln (11) = ln (18) : x = \frac{ln ( 18 )}{ln ( 11 )} - 5

x = \frac{ln ( 18 )}{ln ( 11 )} - 5

2^{1 - x} = 4^{x}

8 (2^{2 x}) + 7 (2^{x}) - 1 = 0

(\frac{1}{3})^{2 n} = 9

1 6^{x - 1} = 6^{4 x}

2^{x^{2} - 4} = 128
