x = \frac{e ^{3} - 4}{5}

Dezimale

x = 3.21710 \dots

Schritte zur Lösung

ln (5 x + 4) = 3

Wende die log Regel an

5 x + 4 = e^{3}

Löse

5 x + 4 = e^{3} : x = \frac{e ^{3} - 4}{5}

x = \frac{e ^{3} - 4}{5}

ln (5 x + 4) = 0

lo g_{0.5} (x) = 2

ln (x + 10) + ln (x - 3) = 2 ln (x)

0 = 2 ln (x)

lo g_{6} (4 x) - 4 lo g_{6} (2) = 0
