<pre>

The starting equation

    {{{log(x,(16))}}} = 4


is equivalent to

    {{{x^4}}} = 16,   x is a real positive number,

or

    {{{x^4}}} = {{{2^4}}},  x is a real positive number.


It has the solution x= 2, and this solution is UNIQUE (which means that there is no other solution).


<U>ANSWER</U>.  x = 2 is the unique solution.
