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

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

x = 9, x = 3

Solution steps

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

Apply log rules

\frac{2}{lo g _{3} ( x )} + lo g_{3} (x) = 3

Rewrite the equation with

lo g_{3} (x) = u

\frac{2}{u} + u = 3

Solve

\frac{2}{u} + u = 3 : u = 2, u = 1

u = 2, u = 1

Substitute back

u = lo g_{3} (x),

solve for

x

Solve

lo g_{3} (x) = 2 : x = 9

Solve

lo g_{3} (x) = 1 : x = 3

x = 9, x = 3

Verify Solutions:

x = 9

True

, x = 3

True

The solutions are

x = 9, x = 3

2.3 = - lo g_{10} (x)

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

8 lo g_{2} (n) = n

lo g_{10} (t) = - 6.016

lo g_{x} (16) = \frac{4}{5}
