log_{9}(x)+log_{9}(x-8)=1

lo g_{9} (x) + lo g_{9} (x - 8) = 1

x = 9

Solution steps

lo g_{9} (x) + lo g_{9} (x - 8) = 1

Apply log rules

x (x - 8) = 9

Solve

x (x - 8) = 9 : x = 9, x = - 1

x = 9, x = - 1

Verify Solutions:

x = 9

True

, x = - 1

False

The solution is

x = 9

2 ln (x) = - 1

lo g_{x} (x + 30) = 2

lo g_{7} (x) = 1.69

ln (x + 15) - ln (3 - 2 x) = 4 ln (2)

a ln (2) = \frac{a}{4} ln (a)
