ln(x^2-2x)=1

Lösung

ln (x^{2} - 2 x) = 1

x = \frac{2 + 4 + 4 e}{2}, x = \frac{2 - 4 + 4 e}{2}

Dezimale

x = 2.92828 \dots, x = - 0.92828 \dots

Schritte zur Lösung

ln (x^{2} - 2 x) = 1

Wende die log Regel an

x^{2} - 2 x = e

Löse

x^{2} - 2 x = e : x = \frac{2 + 4 + 4 e}{2}, x = \frac{2 - 4 + 4 e}{2}

x = \frac{2 + 4 + 4 e}{2}, x = \frac{2 - 4 + 4 e}{2}

so l v e f or x, lo g_{10} (y) = ln (x)

lo g_{10} (n) = 6

lo g_{10} (n) = 1

ln (4 x - 8) = 2

lo g_{10} (- 1 - y) = 0
