ln(x^2-4)=8

Lösung

ln (x^{2} - 4) = 8

x = e^{8} + 4, x = - e^{8} + 4

Dezimale

x = 54.63476 \dots, x = - 54.63476 \dots

Schritte zur Lösung

ln (x^{2} - 4) = 8

Wende die log Regel an

x^{2} - 4 = e^{8}

Löse

x^{2} - 4 = e^{8} : x = e^{8} + 4, x = - e^{8} + 4

x = e^{8} + 4, x = - e^{8} + 4

8 (X)^{2} = 64 X lo g_{2} (X)

lo g_{2} (x + 5) = 0

lo g_{2} (x + 5) = 6

lo g_{10} (p) = - n

so l v e f or v, d = 20 lo g_{10} (v)
