log_{7}(x^3-3x^2+3x-1)=6

Lösung

lo g_{7} (x^{3} - 3 x^{2} + 3 x - 1) = 6

x = 50

Schritte zur Lösung

lo g_{7} (x^{3} - 3 x^{2} + 3 x - 1) = 6

Wende die log Regel an

x^{3} - 3 x^{2} + 3 x - 1 = 117649

Löse

x^{3} - 3 x^{2} + 3 x - 1 = 117649 : x = 50

x = 50

3 ln (2 x) = 15

3 ln (2 x) = 12

3 ln (5 x - 1) + 17 = 29

ln^{3} (x) + 3 ln^{2} (x) = 0

ln (3 x - 16) = 9
