ln(x+8)+ln(x-8)=0

ln (x + 8) + ln (x - 8) = 0

x = 65

Decimal Notation

x = 8.06225 \dots

Solution steps

ln (x + 8) + ln (x - 8) = 0

Apply log rules

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

Solve

(x + 8) (x - 8) = 1 : x = 65, x = - 65

x = 65, x = - 65

Verify Solutions:

x = 65

True

, x = - 65

False

The solution is

x = 65

ln (3 x + 8) = ln (2 x + 2) + ln (x - 2)

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

lo g_{3} (x + 7) = 3

1.034 + 1.4758 = 1.0445 ln (x)

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