The book said Use comparison test But there is another section saying "Limit comparison test"

limit comparison test is easier because it does not have to be smaller

can i make it to k^(4/3)/(8k^2+8k^2+8k^2) just to make it smaller?
anonymous
  • anonymous
so it will become 1/24k^(2/3) and it will pass the p test and smaller

you have to use a function that you know diverges by some rule in this case divergent p series
