Schritte zur Lösung

2^{x} = 127

Wende Exponentenregel an

x ln (2) = ln (127)

Löse

x ln (2) = ln (127) : x = \frac{ln ( 127 )}{ln ( 2 )}

x = \frac{ln ( 127 )}{ln ( 2 )}

2^{x - 9} = 9

so l v e f or x, 4^{x} + 6^{x} = 9^{x}

2 7^{x + 2} = (\frac{1}{9})^{2 x + 4}

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

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