2log_{5}(x)-log_{5}(x+6)=2

2 lo g_{5} (x) - lo g_{5} (x + 6) = 2

x = 30

Solution steps

2 lo g_{5} (x) - lo g_{5} (x + 6) = 2

Apply log rules

x^{2} = 25 (x + 6)

Solve

x^{2} = 25 (x + 6) : x = 30, x = - 5

x = 30, x = - 5

Verify Solutions:

x = 30

True

, x = - 5

False

The solution is

x = 30

20 lo g_{10} (1 + x) = 0.1

20 + ln (5) = 2 ln (x)

lo g_{8} (lo g_{5} (x)) = 0

0 = 80 - 10 lo g_{2} (t + 1)

lo g_{x} (\frac{1}{125}) = - 9
