ln(x)+ln(x+4)=ln(15)+ln(3)

ln (x) + ln (x + 4) = ln (15) + ln (3)

x = 5

Solution steps

ln (x) + ln (x + 4) = ln (15) + ln (3)

Apply log rules

x (x + 4) = 45

Solve

x (x + 4) = 45 : x = 5, x = - 9

x = 5, x = - 9

Verify Solutions:

x = 5

True

, x = - 9

False

The solution is

x = 5

lo g_{10} (x) = 207

lo g_{10} (x) = 232

30 = 10 lo g_{10} (n)

lo g_{9} (x) = a lo g_{3} (x)

34 = 10 lo g_{10} (g)
