log_{3}(x^2-x-5)=2

Lösung

lo g_{3} (x^{2} - x - 5) = 2

Lösung

x = \frac{1 + 57}{2}, x = \frac{1 - 57}{2}

+1

Dezimale

x = 4.27491 \dots, x = - 3.27491 \dots

Schritte zur Lösung

lo g_{3} (x^{2} - x - 5) = 2

Wende die log Regel an

x^{2} - x - 5 = 9

Löse

x^{2} - x - 5 = 9 : x = \frac{1 + 57}{2}, x = \frac{1 - 57}{2}

x = \frac{1 + 57}{2}, x = \frac{1 - 57}{2}
