ln(x+1)+ln(x+3)=ln(x+7)

ln (x + 1) + ln (x + 3) = ln (x + 7)

x = 1

Solution steps

ln (x + 1) + ln (x + 3) = ln (x + 7)

Apply log rules

(x + 1) (x + 3) = x + 7

Solve

(x + 1) (x + 3) = x + 7 : x = 1, x = - 4

x = 1, x = - 4

Verify Solutions:

x = 1

True

, x = - 4

False

The solution is

x = 1

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

lo g_{x} (\frac{1}{81}) = 4

6 = ln (s)

9^{l o g_{3} (x)} = x - 2 x^{2} + 4

ln (3 x - 14) = 4
