Schritte zur Lösung

57 = 1 1^{x}

Wende Exponentenregel an

ln (57) = x ln (11)

Löse

ln (57) = x ln (11) : x = \frac{ln ( 57 )}{ln ( 11 )}

x = \frac{ln ( 57 )}{ln ( 11 )}

5^{x + 3} = 625

so l v e f or x, f = (\frac{1}{m})^{x}

3^{x + 1} - 8 (3^{x - 1}) - 5 = 0

\frac{1}{100} = e^{- 0.15 t}

6^{5 x - 1} - 2 = 1
