1. The problem statement, all variables and given/known data Ʃ (1+n+n2)/(√1+n2+n6)) n=1 to infinity Answer is divergent 2. Relevant equations Comparison Test / P Series 0≤an≤bn 3. The attempt at a solution Hello, I simplified the problem to Ʃ (1+n+n2)/(1+n2+n6)1/2 Is it incorrect of me to say immediately right here that because the power of the denominator p<1 it is divergent? Or if I take a different approach use comparison test and say 0≤an≤1/(1+n2+n6)1/2 can I say it is divergent because bn is divergent due to p-series? WA says it is divergent due to comparison test but how would I get something like say 1/n^6 out of that square root to use as bn?
