ln(x)+ln(x+2)=0

ln (x) + ln (x + 2) = 0

x = - 1 + 2

Decimal Notation

x = 0.41421 \dots

Solution steps

ln (x) + ln (x + 2) = 0

Apply log rules

x (x + 2) = 1

Solve

x (x + 2) = 1 : x = - 1 + 2, x = - 1 - 2

x = - 1 + 2, x = - 1 - 2

Verify Solutions:

x = - 1 + 2

True

, x = - 1 - 2

False

The solution is

x = - 1 + 2

lo g_{3} (x - 5) = lo g_{3} (x - 5)

lo g_{3} (7 x - 2) = 5

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

lo g_{10} (2 x - 1) = \frac{1}{2}

lo g_{10} (x) = - 6
