x = \frac{ln ( 2 )}{ln ( 7 )}

Dezimale

x = 0.35620 \dots

Schritte zur Lösung

7^{x} = 2

Wende Exponentenregel an

x ln (7) = ln (2)

Löse

x ln (7) = ln (2) : x = \frac{ln ( 2 )}{ln ( 7 )}

x = \frac{ln ( 2 )}{ln ( 7 )}

7^{x} = 1

8^{x + 1} = 2^{2 x + 3}

(0.5)^{(\frac{9900}{x})} = 0.3

\frac{2}{3 ^{x - 5}} = 162

7^{2 x + 1} = 3^{x + 2}
