ln(x^2-4)=ln(x+2)

ln (x^{2} - 4) = ln (x + 2)

x = 3

Solution steps

ln (x^{2} - 4) = ln (x + 2)

Apply log rules

x^{2} - 4 = x + 2

Solve

x^{2} - 4 = x + 2 : x = 3, x = - 2

x = 3, x = - 2

Verify Solutions:

x = 3

True

, x = - 2

False

The solution is

x = 3

x \cdot ln (x) + x = 0

p, - 100 = 10 lo g_{10} (p)

lo g_{10} (x) = 3.8192

26 ln (4 x - 5) = 3 + ln (e^{10})

x, ln (x) = 1 - v + ln (1 - v)
