Lösung

3^{x} = 4

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

Dezimale

x = 1.26185 \dots

Schritte zur Lösung

3^{x} = 4

Wende Exponentenregel an

x ln (3) = ln (4)

Löse

x ln (3) = ln (4) : x = \frac{2 ln ( 2 )}{ln ( 3 )}

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

e^{x} + 1 = 2

so l v e f or t, x = e^{t}

2^{x + 2} = 16

e^{2 x} = 4

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