t = \frac{ln ( 11 )}{ln ( 7 )}

Dezimale

t = 1.23227 \dots

Schritte zur Lösung

7^{t} = 11

Wende Exponentenregel an

t ln (7) = ln (11)

Löse

t ln (7) = ln (11) : t = \frac{ln ( 11 )}{ln ( 7 )}

t = \frac{ln ( 11 )}{ln ( 7 )}

2^{2 x + 1} - 13 (2^{x}) = 24

2 5^{x} - 9 \cdot 5^{x} + 20 = 0

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

(\frac{1}{2})^{x} = \frac{1}{16}

78 \cdot 1.05 5^{t} = 110
