log_{3}(x^2-24x)=4

Lösung

lo g_{3} (x^{2} - 24 x) = 4

x = 27, x = - 3

Schritte zur Lösung

lo g_{3} (x^{2} - 24 x) = 4

Wende die log Regel an

x^{2} - 24 x = 81

Löse

x^{2} - 24 x = 81 : x = 27, x = - 3

x = 27, x = - 3

1 + 3 lo g_{10} (2 x) = 4

ln (x) = \frac{1}{6}

2 ln (x) = ln (4)

ln (x^{2} + 1) = 8

ln (x + 8) = 3
