x = 2.08496 \dots

Schritte zur Lösung

4^{x} = 18

Wende Exponentenregel an

x ln (4) = ln (18)

Löse

x ln (4) = ln (18) : x = \frac{ln ( 18 )}{2 ln ( 2 )}

x = \frac{ln ( 18 )}{2 ln ( 2 )}

e^{5 x} = 9

\frac{1}{27} = 3^{4 m - 1}

3^{x} = 5^{2 x - 1}

so l v e f or x, 2^{x + 3} = 4^{x - 2}

30000 = 50 \cdot 3^{t}
