ln(x+1)+ln(x-1)=ln(8)

ln (x + 1) + ln (x - 1) = ln (8)

x = 3

Solution steps

ln (x + 1) + ln (x - 1) = ln (8)

Apply log rules

(x + 1) (x - 1) = 8

Solve

(x + 1) (x - 1) = 8 : x = 3, x = - 3

x = 3, x = - 3

Verify Solutions:

x = 3

True

, x = - 3

False

The solution is

x = 3

3 lo g_{10} (4 x) - 2 lo g_{10} (2) = 0

lo g_{2} (4 x + 4) + lo g_{2} (x + 1) = 0

x, ln (x + y) = 0

7 lo g_{9} (x + 8) = 14

lo g_{6} (x - 10) + lo g_{6} (7) = 2
