what would be an appropriate test (out of ratio, intergral, limit comparison) to decide if the series sum of(1 to infinity)[k^(1/2)/ ] converges or diverges?

you can use ratio test I prefer it

so would it be ok use k^(1/2)/k^3 as Bn in the limit comparison test?
No i think it will be the same take
