Lösung

ln (5 - 2 x) = - 3

x = \frac{- 1 + 5 e ^{3}}{2 e ^{3}}

Dezimale

x = 2.47510 \dots

Schritte zur Lösung

ln (5 - 2 x) = - 3

Wende die log Regel an

5 - 2 x = \frac{1}{e ^{3}}

Löse

5 - 2 x = \frac{1}{e ^{3}} : x = \frac{- 1 + 5 e ^{3}}{2 e ^{3}}

x = \frac{- 1 + 5 e ^{3}}{2 e ^{3}}

ln (\frac{15}{13 - 2 x}) = ln (x)

lo g_{2} (lo g_{3} (x)) = 2

ln (x - 2) + ln (x + 1) = 2 ln (2)

lo g_{x} (32) = \frac{5}{2}

lo g_{2} (x) = - 1
