log_{4}(x-5)+log_{4}(x+3)=1

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

x = 1 + 25

Solution steps

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

Apply log rules

(x - 5) (x + 3) = 4

Solve

(x - 5) (x + 3) = 4 : x = 1 + 25, x = 1 - 25

x = 1 + 25, x = 1 - 25

Verify Solutions:

x = 1 + 25

True

, x = 1 - 25

False

The solution is

x = 1 + 25

lo g_{10} (200) = 4 - 3 lo g_{10} (x)

lo g_{7} (w) - lo g_{7} (13) = 1

10 - 2 lo g_{10} (x - 3) = 8

lo g_{x} (2) = - 3

lo g_{a} (36) = 2
