log_{8}(x)-2log_{x}(8)=1

lo g_{8} (x) - 2 lo g_{x} (8) = 1

x = 64, x = \frac{1}{8}

Decimal Notation

x = 64, x = 0.125

Solution steps

lo g_{8} (x) - 2 lo g_{x} (8) = 1

Apply log rules

lo g_{8} (x) - \frac{2}{lo g _{8} ( x )} = 1

Rewrite the equation with

lo g_{8} (x) = u

u - \frac{2}{u} = 1

Solve

u - \frac{2}{u} = 1 : u = 2, u = - 1

u = 2, u = - 1

Substitute back

u = lo g_{8} (x),

solve for

x

Solve

lo g_{8} (x) = 2 : x = 64

Solve

lo g_{8} (x) = - 1 : x = \frac{1}{8}

x = 64, x = \frac{1}{8}

Verify Solutions:

x = 64

True

, x = \frac{1}{8}

True

The solutions are

x = 64, x = \frac{1}{8}

ln (2 v + 7) = ln (3 v)

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

lo g_{4} (x) - lo g_{4} (x - 9) = 1

4 lo g_{3} (x) = lo g_{3} (x^{4})

5 lo g_{9} (2) = lo g_{9} (z)
