log_{2}(x+7)+log_{2}(x)=3

lo g_{2} (x + 7) + lo g_{2} (x) = 3

x = 1

Solution steps

lo g_{2} (x + 7) + lo g_{2} (x) = 3

Apply log rules

(x + 7) x = 8

Solve

(x + 7) x = 8 : x = 1, x = - 8

x = 1, x = - 8

Verify Solutions:

x = 1

True

, x = - 8

False

The solution is

x = 1

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

1 - ln (x) = 0

lo g_{3} (x) - 2 lo g_{x} (3) = 1

2 lo g_{3} (x) - lo g_{3} (x - 2) = 2

lo g_{4} (x - 1) + lo g_{4} (x + 2) = 1
