Schritte zur Lösung

1.41 = 2^{x}

Wende Exponentenregel an

ln (1.41) = x ln (2)

Löse

ln (1.41) = x ln (2) : x = \frac{ln ( 1.41 )}{ln ( 2 )}

x = \frac{ln ( 1.41 )}{ln ( 2 )}

(\frac{8}{9})^{3} \cdot (\frac{8}{9})^{- 6} = (\frac{8}{9})^{2 x - 1}

3^{2 x - 2} = 81

- (\frac{5}{4}) = (\frac{- 4}{5})^{x}

2^{2} x + 3 + 7 = 15. 2^{x}

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