x = - \frac{ln ( 565 ) - 3 ln ( 2 )}{ln ( 2 )}

Dezimale

x = - 6.14210 \dots

Schritte zur Lösung

2^{3 - x} = 565

Wende Exponentenregel an

(3 - x) ln (2) = ln (565)

Löse

(3 - x) ln (2) = ln (565) : x = - \frac{ln ( 565 ) - 3 ln ( 2 )}{ln ( 2 )}

x = - \frac{ln ( 565 ) - 3 ln ( 2 )}{ln ( 2 )}

so l v e f or x, 2^{x} = \frac{1}{2}

4 e^{x - 2} = 91

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

4^{2 x} - 3 (4^{x}) = - 2

x^{0.2} = 2^{x}
