The logarithm equation is $\"\"$ .

Apply quotient property of logarithm : $\"\"$ .

$\"\"$

Apply one-to-one property of logarithm function : $\"\"$ if and only if $\"\"$ .

$\"\"$

Check logarithm equation at $\"\"$ .

Substitute $\"\"$ in $\"\"$ .

$\"\"$

The domain of logarithm is : $\"\"$ .

$\"\"$ and $\"\"$ is not in the domain of logarithm.

Hence $\"\"$ is not a solution.

The logarithm equation $\"\"$ has no solution.
