What is the following equation about?

(a+b^n)/n = x

It has too many unknowns.  There seem to be too many trivial solutions: a=b=n=1, x=2 or a=1, b=2, n=3, x=3 or a=2, b=2, n=2, x=3 and on and on.  Why would anyone think that this has anything to do with the existance of God?

The following is from en.wikipedia.org/wiki/Leonhard_Euler

There is a famous anecdote inspired by Euler's arguments with secular philosophers over religion, which is set during Euler's second stint at the St. Petersburg academy. The French philosopher Denis Diderot was visiting Russia on Catherine the Great's invitation. However, the Empress was alarmed that the philosopher's arguments for atheism were influencing members of her court, and so Euler was asked to confront the Frenchman. Diderot was later informed that a learned mathematician had produced a proof of the existence of God: he agreed to view the proof as it was presented in court. Euler appeared, advanced toward Diderot, and in a tone of perfect conviction announced, "Sir, , hence God exists—reply!". Diderot, to whom (says the story) all mathematics was gibberish, stood dumbstruck as peals of laughter erupted from the court. Embarrassed, he asked to leave Russia, a request that was graciously granted by the Empress. However amusing the anecdote may be, it is almost certainly apocryphal, given that Diderot was a capable mathematician who had published mathematical treatises.
