ln(x+2)+ln(x)=ln(x+20)

ln (x + 2) + ln (x) = ln (x + 20)

x = 4

Solution steps

ln (x + 2) + ln (x) = ln (x + 20)

Apply log rules

(x + 2) x = x + 20

Solve

(x + 2) x = x + 20 : x = 4, x = - 5

x = 4, x = - 5

Verify Solutions:

x = 4

True

, x = - 5

False

The solution is

x = 4

ln (- y + 4) - ln (y + 3) = ln (- 3 y + 1)

lo g_{10} (x) 16 = - 2

lo g_{2} (2 x + 3) = 4

x, 0.47 = lo g_{10} (x)

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