log_{6}(x^2+9x)=2

Lösung

lo g_{6} (x^{2} + 9 x) = 2

x = 3, x = - 12

Schritte zur Lösung

lo g_{6} (x^{2} + 9 x) = 2

Wende die log Regel an

x^{2} + 9 x = 36

Löse

x^{2} + 9 x = 36 : x = 3, x = - 12

x = 3, x = - 12

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

lo g_{4} (x) = - 4

lo g_{4} (x) = - 8

ln (5 x + e) = 3

lo g_{4} (x) = 12
