Lösung

3^{2 x + 5} = 7^{x}

x = - \frac{5 ln ( 3 )}{2 ln ( 3 ) - ln ( 7 )}

Dezimale

x = - 21.85732 \dots

Schritte zur Lösung

3^{2 x + 5} = 7^{x}

Wende Exponentenregel an

(2 x + 5) ln (3) = x ln (7)

Löse

(2 x + 5) ln (3) = x ln (7) : x = - \frac{5 ln ( 3 )}{2 ln ( 3 ) - ln ( 7 )}

x = - \frac{5 ln ( 3 )}{2 ln ( 3 ) - ln ( 7 )}

e^{4 x} = \frac{1}{64}

7^{- 3 x} = 1 1^{x + 8}

3^{x} = - 2 in

7^{- x} = 2

2^{3 y} - 2^{2 y} - 2^{y + 1} = 0
