Lösung

ln (x + 4) = - 2

x = \frac{1}{e ^{2}} - 4

Dezimale

x = - 3.86466 \dots

Schritte zur Lösung

ln (x + 4) = - 2

Wende die log Regel an

x + 4 = \frac{1}{e ^{2}}

Löse

x + 4 = \frac{1}{e ^{2}} : x = \frac{1}{e ^{2}} - 4

x = \frac{1}{e ^{2}} - 4

lo g_{10} (0.3 x) = - 2

lo g_{3} (lo g_{10} (9 x) + 12 + 9^{x}) = 2 x

ln (x - 1) = 4.4

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

0.26 = lo g_{10} (x)
