log_{81}(x)=-1/4

Lösung

lo g_{81} (x) = - \frac{1}{4}

x = \frac{1}{3}

Dezimale

x = 0.33333 \dots

Schritte zur Lösung

lo g_{81} (x) = - \frac{1}{4}

Wende die log Regel an

x = \frac{1}{3}

5 ln (4 x - 9) + 7 = - 8

ln (n^{2} + 2 n + 1) = 0

3 ln (2 x) = - 3

lo g_{16} (5 x - 2) = \frac{3}{4}

so l v e f or x, 0 = ln (x)
