log_{2}(x^2-x-6)=2

Lösung

lo g_{2} (x^{2} - x - 6) = 2

Lösung

x = \frac{1 + 41}{2}, x = \frac{1 - 41}{2}

+1

Dezimale

x = 3.70156 \dots, x = - 2.70156 \dots

Schritte zur Lösung

lo g_{2} (x^{2} - x - 6) = 2

Wende die log Regel an

x^{2} - x - 6 = 4

Löse

x^{2} - x - 6 = 4 : x = \frac{1 + 41}{2}, x = \frac{1 - 41}{2}

x = \frac{1 + 41}{2}, x = \frac{1 - 41}{2}

solvefor x,ln(x)-ln(x-2)=1

so l v e f or x, ln (x) - ln (x - 2) = 1

log_{2}(x+1)+log_{2}(x+2)=1

lo g_{2} (x + 1) + lo g_{2} (x + 2) = 1

ln(1-x)+ln(1+x)=-2

ln (1 - x) + ln (1 + x) = - 2

solvefor y,z=ln(y+2)-ln(y+1)

so l v e f or y, z = ln (y + 2) - ln (y + 1)

ln (x + 4) = 0
