Question #a1d99

Answer 1

Impossible

Explanation:

We 'assume' that n is an integer. This means 2n is always an even integer.
The left hand side term is `-1^(2n)` this is always equal to 1.
Or if we read the left hand term differently as `-(1^(2n))`, then the term is always -1.
The right hand term is `1^3` + `5^8` which is way bigger than 1 or -1
So in both interpretations of -1^2n the question has no solution for n.

Am I missing something here?
