The exponetial equation is $\"\"$ .

\

Consider $\"\"$ .

\

$\"\"$

\

$\"\"$ and $\"\"$

\

$\"\"$ and $\"\"$ .

\

$\"\"$ and $\"\"$ .

\

$\"\"$

\

Case 1 :

\

The exponential equation is $\"\"$ .

\

Apply logarithm on each side.

\

$\"\"$

\

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

\

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

\

Hence there is no solution.

\

$\"\"$

\

Case 2 :

\

The exponential equation is $\"\"$ .

\

Apply logarithm on each side.

\

$\"\"$ .

\

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

\

$\"\"$

\

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

\

$\"\"$
