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

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

x = 2

Solution steps

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

Apply log rules

(x + 2) x = 8

Solve

(x + 2) x = 8 : x = 2, x = - 4

x = 2, x = - 4

Verify Solutions:

x = 2

True

, x = - 4

False

The solution is

x = 2

lo g_{3} (5 x + 1) = 4

lo g_{2} (x) = - 4

0.27 = lo g_{10} (x)

2 ln (x + 3) = 0

0.9 = lo g_{10} (x)
