220 = 2^{x}

x = \frac{ln ( 220 )}{ln ( 2 )}

Dezimale

x = 7.78135 \dots

Schritte zur Lösung

220 = 2^{x}

Wende Exponentenregel an

ln (220) = x ln (2)

Löse

ln (220) = x ln (2) : x = \frac{ln ( 220 )}{ln ( 2 )}

x = \frac{ln ( 220 )}{ln ( 2 )}

so l v e f or x, 1 = e^{2 x - 3} - 5

5 = 5 + 16 e^{k (34)}

(\frac{1}{8})^{x} = 512

\frac{- e ^{x} + 2}{3} = 0

2 5^{\frac{x}{2}} = 12 5^{x + 3}
