Solution

x = \frac{1}{7 e ^{2}}

+1

Decimal Notation

x = 0.01933 \dots

Solution steps

ln (7 x) = - 2

Apply log rules

7 x = \frac{1}{e ^{2}}

Solve

7 x = \frac{1}{e ^{2}} : x = \frac{1}{7 e ^{2}}

Popular Examples

log_{10}(x-4)=2

lo g_{10} (x - 4) = 2

log_{10}(10x)=-2

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

log_{10}(x)=1+log_{10}(22-x)

lo g_{10} (x) = 1 + lo g_{10} (22 - x)

2log_{10}(x)=(3+log_{10}(x))/(10)

2 lo g_{10} (x) = \frac{3 + lo g _{10} ( x )}{10}

lo g_{2} (x^{2}) = 1
