log_{2}(x^2-5x-4)=1

Lösung

lo g_{2} (x^{2} - 5 x - 4) = 1

Lösung

x = 6, x = - 1

Schritte zur Lösung

lo g_{2} (x^{2} - 5 x - 4) = 1

Wende die log Regel an

x^{2} - 5 x - 4 = 2

Löse

x^{2} - 5 x - 4 = 2 : x = 6, x = - 1

log_{x}(256)=-8

lo g_{x} (256) = - 8

log_{10}(x)-log_{10}(8)=3

lo g_{10} (x) - lo g_{10} (8) = 3

log_{10}(x+12)=log_{10}(x)+log_{10}(12)

lo g_{10} (x + 12) = lo g_{10} (x) + lo g_{10} (12)

lo g_{3} (x) = - 5

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

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