The starting equation

    log%28x%2C%2816%29%29 = 4


is equivalent to

    x%5E4 = 16,   x is a real positive number,

or

    x%5E4 = 2%5E4,  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).


ANSWER.  x = 2 is the unique solution.

Solved.
