ln(9x)+1=0

Solution

ln (9 x) + 1 = 0

Solution

x = \frac{1}{9 e}

+1

Decimal

x = 0.04087 \dots

Solution steps

ln (9 x) + 1 = 0

Move

1

to the right side

ln (9 x) = - 1

Apply log rules

9 x = \frac{1}{e}

Solve

9 x = \frac{1}{e} : x = \frac{1}{9 e}

x = \frac{1}{9 e}

Verify Solutions:

x = \frac{1}{9 e}

True

The solution is

x = \frac{1}{9 e}

lo g_{5} (x + 1) = 3

log_{10}(sqrt(3x+5))+log_{10}(sqrt(x))=1

lo g_{10} (3 x + 5) + lo g_{10} (x) = 1

log_{x}(7)= 1/3

lo g_{x} (7) = \frac{1}{3}

-3=log_{x}(1/8)

- 3 = lo g_{x} (\frac{1}{8})
