ln(x)+ln(x+2)=ln(15)

ln (x) + ln (x + 2) = ln (15)

x = 3

Solution steps

ln (x) + ln (x + 2) = ln (15)

Apply log rules

x (x + 2) = 15

Solve

x (x + 2) = 15 : x = 3, x = - 5

x = 3, x = - 5

Verify Solutions:

x = 3

True

, x = - 5

False

The solution is

x = 3

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

16.04 = 10 \cdot lo g_{10} (x)

lo g_{10} (x + 1) = - 1

2 ln (4 x) = 2 ln (8)

lo g_{5} (x) + lo g_{25} (x) = 3
