ln((x+2)^2)=12

Lösung

ln ((x + 2)^{2}) = 12

x = e^{6} - 2, x = - e^{6} - 2

Dezimale

x = 401.42879 \dots, x = - 405.42879 \dots

Schritte zur Lösung

ln ((x + 2)^{2}) = 12

Wende die log Regel an

(x + 2)^{2} = e^{12}

Löse

(x + 2)^{2} = e^{12} : x = e^{6} - 2, x = - e^{6} - 2

x = e^{6} - 2, x = - e^{6} - 2

ln (3 x + 9) = 2 x - 3

lo g_{2} (x) = 12

lo g_{4} (x^{2} + 15) = 3

ln (3 x + 2) = ln (5 x - 6)

so l v e f or a, lo g_{10} (a) = 3
