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

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

x = 5

Decimal Notation

x = 2.23606 \dots

Solution steps

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

Apply log rules

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

Solve

(x - 2) (x + 2) = 1 : x = 5, x = - 5

x = 5, x = - 5

Verify Solutions:

x = 5

True

, x = - 5

False

The solution is

x = 5

lo g_{10} (x^{2} - 6 x + 8) - 1 = 0

x, lo g_{10} (25 x) = 3

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

lo g_{7} (4 x - 3) = 3

ln ((x + 1)^{2}) = 2 ln (x + 1)
