Simplifying exponential fraction



I have this exponential fraction
2n+15n1



I was wondering how we simplify something like this.




I know if the top and bottom had the same like 2n+12n+1, you would just subtract the exponent.



But in my situation, I'm not too sure how to tackle it.


Answer



2n+15n1=2×5×2n5n=10×(25)n=10×0.4n if you wish. But if you are dealing with simplifying fractions, I do think your answer is fine.
