log_{3}(x^2-x-4)=2

Lösung

lo g_{3} (x^{2} - x - 4) = 2

x = \frac{1 + 53}{2}, x = \frac{1 - 53}{2}

Dezimale

x = 4.14005 \dots, x = - 3.14005 \dots

Schritte zur Lösung

lo g_{3} (x^{2} - x - 4) = 2

Wende die log Regel an

x^{2} - x - 4 = 9

Löse

x^{2} - x - 4 = 9 : x = \frac{1 + 53}{2}, x = \frac{1 - 53}{2}

x = \frac{1 + 53}{2}, x = \frac{1 - 53}{2}

lo g_{4} (x) - 4 lo g_{x} (4) + 3 = 0

0.54 = ln (y)

ln (4 x) = 2.0706

lo g_{10} (h) = 1

lo g_{2} ((r + 11)^{2}) = 4
