log_{3}(x+7)+log_{3}(x+5)=1

lo g_{3} (x + 7) + lo g_{3} (x + 5) = 1

x = - 4

Solution steps

lo g_{3} (x + 7) + lo g_{3} (x + 5) = 1

Apply log rules

(x + 7) (x + 5) = 3

Solve

(x + 7) (x + 5) = 3 : x = - 4, x = - 8

x = - 4, x = - 8

Verify Solutions:

x = - 4

True

, x = - 8

False

The solution is

x = - 4

lo g_{b} (8) = - \frac{1}{2}

1 + ln (3 x) = 0

lo g_{10} (x) = 0.17527

ln (7 x + 2) = 3

lo g_{5} (x) + 2 lo g_{5} (3) = 2
