ln(2x)=-1

Solution

ln (2 x) = - 1

Solution

x = \frac{1}{2 e}

+1

Decimal Notation

x = 0.18393 \dots

Solution steps

ln (2 x) = - 1

Apply log rules

2 x = \frac{1}{e}

Solve

2 x = \frac{1}{e} : x = \frac{1}{2 e}

x = \frac{1}{2 e}

Popular Examples

log_{4}(3w+1)=2

lo g_{4} (3 w + 1) = 2

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

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

log_{10}(x+1)=3

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

log_{4}(x-1)=log_{2}(x-3)

lo g_{4} (x - 1) = lo g_{2} (x - 3)

log_{5}(x)+log_{x}(5)=2

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