log_{3}(x)=-4

Lösung

lo g_{3} (x) = - 4

x = \frac{1}{81}

Dezimale

x = 0.01234 \dots

Schritte zur Lösung

lo g_{3} (x) = - 4

Wende die log Regel an

x = \frac{1}{81}

ln (x) + ln (x + 2) = 4

lo g_{5} (x - 7) = 1 - lo g_{5} (x - 3)

ln (x) + ln (x) = 0

lo g_{x} (9) = \frac{2}{3}

ln (x) - ln (\frac{1}{x}) = 2
